A circuit breaker is an automatic electrical switch designed to
protect an electrical circuit from damage caused by an overload or a
short circuit. Its fundamental function is to interrupt current flow
when a fault is detected. Unlike a fuse, which operates once and then
must be replaced, a circuit breaker can be reset, either manually or
automatically, to resume normal operation. Essentially, a circuit
breaker is the guardian of a plethora of electrical devices, ensuring
they are safe from erratic flows of electricity. As such, it is a
crucial component of any home or industrial electrical system.
Importance and Role of
Circuit Breaker
Circuit breakers play a crucial role in safeguarding our homes and
our power systems. They are the unsung heroes that shield electrical
circuits from damage caused by overload or short circuits. When a fault
is detected, a circuit breaker will automatically ‘trip’ or break the
circuit, efficiently disrupting the flow of electric current. This
prevents wires from overheating and potentially starting fires, ensuring
the safety of our buildings and appliances.
Beyond serving as havens against electrical mishaps, circuit breakers
also facilitate power management. In instances where electrical
maintenance or repairs are needed, they allow for specific sections of
an electrical system to be shut down without disrupting power elsewhere.
This feature furthers their role in maintaining uninterrupted
operations, particularly in commercial installations.
In essence, circuit breakers are vital components within electrical
systems, promoting operational efficiency, safety, and sustainability.
Without them, we would be constantly exposed to the risks associated
with electrical faults or overloads.
Basics of Circuit Breaker
Maintenance
What Constitutes
Circuit Breaker Maintenance
Circuit breaker maintenance is a comprehensive process involving
several procedures aimed at ensuring the functionality, safety and
longevity of the circuit breaker. This typically includes regular visual
inspections to check for any signs of damage, wear and tear, or abnormal
operation. Cleaning is an essential part of this procedure, which
provides a clean path for the electric current and helps prevent short
circuits.
Mechanical checks follow the cleaning to confirm the moving parts
within the system are functioning optimally, and to detect any loose
fittings, which may be hazardous. Electrical checks and tests evaluate
the continuity of circuits, insulation resistance, and identify any
potential electrical faults that may disrupt the operation of the
device.
Lastly, lubrication of moving parts aids in the smooth operation of
the circuit breaker, minimising wear and tear due to friction.
Components like the operating mechanism, linkages, and rolling surfaces
are frequently targeted for lubrication. Great care should be taken to
ensure only specified lubricants are used, and excessive oiling doesn’t
lead to clogging.
All these tasks together constitute the process of circuit breaker
maintenance, which is vital to ensure the safe and efficient operation
of electrical circuits in a premise. The complexity and specific nature
of the procedures underline the need for technical knowledge in
performing them.
Why Circuit
Breaker Maintenance is Essential
Circuit breaker maintenance is crucial for several reasons. The most
significant being, ensuring the overall safety of a property and its
inhabitants. An optimally functioning circuit breaker can help prevent
electrical fires by cutting off the flow of electricity when a fault is
detected. Without maintenance, a circuit breaker may fail to perform
this key task, leading to a high risk of fire.
Another reason is to maintain the efficiency of your electrical
system. Over time, dust, rust, and other forms of corrosion can
compromise the performance of your circuit breaker. Regular maintenance
can help detect and address these issues, thus preventing costly repairs
or replacements down the line.
Maintenance also prolongs the lifespan of a circuit breaker. By
addressing issues in a timely manner, you are able to use your breaker
for a longer period, saving you the cost and inconvenience of frequent
replacements.
Finally, continuous maintenance ensures compliance with electrical
codes and standards. It’s important that your building or site meets the
electrical safety regulations imposed by relevant authorities and
maintaining your circuit breaker aids in fulfilling such
requirements.
All these reasons make it clear, why maintaining your circuit breaker
is not just recommended, but absolutely essential.
Types of Circuit Breakers
Air Circuit Breaker
The Air Circuit Breaker (ACB) is one of the common types of circuit
breakers used in low voltage applications where the voltage does not
exceed 1000 volts. The distinguishing feature of an ACB is its use of
air as the arc extinction medium.
An air circuit breaker operates by creating an arc between fixed and
moving contacts that are housed in an ‘arc chute’. When a fault arises,
these contacts separate, and the electromechanical trip unit initiates
current interruption. The arc forms in this gap, and the air helps to
quench the arc when the breaker disconnects the faulted circuit.
There are two types of ACBs – the plain air circuit breaker, where
the blast of air targets the arc when a high-rated current flows, and
the Air Blast Circuit Breaker, where high air pressure is used to
extinguish the arc when the contacts start to disconnect.
The ACBs are commonly used in large commercial and industrial
applications, they are reliable, have good current carrying capability,
and offer a good earth leakage protection. For their maintenance, it is
essential to ensure that the mechanical components are free of dust and
corrosion, and the electrical connections are intact. An occasional
light lubrication of the moving elements helps to maintain the smooth
operation of the ACB.
Vacuum Circuit Breaker
Vacuum Circuit Breakers, also known as VCBs, are another type of
circuit breaker technology. They are often used for medium-voltage range
applications, usually from 3.3kV to 33kV.
The distinguishing feature of the Vacuum Circuit Breaker is its
vacuum interrupter. This is housed in a highly insulated environment,
which ensures that the vacuum inside the breaker is completely sealed
off from the external atmosphere.
The Vacuum Circuit Breaker functions by relying on the high
dielectric strength of the vacuum. When there is a short circuit or
overcurrent, a current path is created inside the vacuum interrupter.
The contact inside the vacuum interrupter is then separated. As these
contacts are being parted, a small arc of current is produced. The
vacuum inside the interrupter helps to extinguish this arc.
One of the main benefits of Vacuum Circuit Breakers is that they
require very minimal maintenance compared to other types of breakers.
They also have long mechanical life expectancy and are less harmful to
the environment since they do not produce harmful gases during
operation. However, they are generally more expensive and work best in
certain voltage limits. In the next part, we will touch on the
maintenance practices appropriate for this type of breaker.
SF6 Circuit Breaker
SF6 Circuit Breakers are named for the sulfur hexafluoride (SF6) gas
they use as an insulator and arc extinguishing medium. This gas, known
for its outstanding insulating properties, allows SF6 circuit breakers
to interrupt high levels of electrical current more efficiently and
compactly.
These types of breakers are largely used in electrical power systems,
including railway and metro systems, wind power facilities, and
utilities. They can successfully manage voltages from 12kV to 765kV,
with interrupting capacities from 25kA to 100kA.
Regarding maintenance, SF6 circuit breakers generally require limited
attention. Regular monitoring of the SF6 gas pressure and quality is
important. In case of a gas leak, qualified personnel should rectify the
issue, as working with SF6 gas requires special skills and handling
knowledge. Furthermore, the gas is tightly controlled for environmental
reasons, due to its high global warming potential.
With good maintenance, SF6 circuit breakers can have a life
expectancy of 20 to 30 years. However, replacement parts can be
challenging to source for older models if a failure does occur, so
maintenance planning should consider this aspect.
Oil Circuit Breaker
Oil circuit breakers are one of the oldest types of circuit breakers,
offering reliable performance under heavy load conditions. They employ
some form of oil as an arc quenching medium. The oil not only acts as an
insulator but also dissipates the heat produced by the arc.
Oil circuit breakers are sub-divided into two types – bulk oil
circuit breaker (BOCB) and minimum oil circuit breaker (MOCB). In bulk
oil circuit breakers, the whole system is immersed in the insulating oil
whereas, in minimum oil circuit breakers, only the arc quenching chamber
contains oil.
Key to the maintenance strategy is regular replacement of this oil.
Over time, dirt or other impurities can lead to deterioration of its
insulating properties. An oil sample should be taken and analyzed during
maintenance schedules to verify it continues to have good dielectric
strength. If not, the oil needs to be changed. Also, the condition of
the oil is a good indicator of the overall fitness of the breaker –
discolored or dirty oil potentially indicates other issues with the
breaker that may need addressing.
Oil circuit breakers, due to their fluid nature, make regular
physical inspections necessary. Any leaks or spills should be promptly
addressed, as well as being aware of the potential fire risk in certain
environments due to the presence of the oil. It’s important to ensure
that the enclosing spaces of the breaker are well-sealed to prevent oil
leakage and ingress of contaminants.
Maintenance practices for
each type
Each type of circuit breaker has its peculiarities which influence
the appropriate maintenance practices.
- For an Air Circuit Breaker (ACB), the air vents must be cleared
regularly to prevent blockages that might impair performance. Check for
wear and tear particularly in components like the arc chute since the
ACB depends on the air for the extinction of arc. - When dealing with a Vacuum Circuit Breaker (VCB), the vacuum
should be tested for its pressure. Additionally, the movement mechanism
should be periodically checked to ensure its smooth
functioning. - The maintenance of an SF6 Circuit Breaker requires taking
readings of the gas pressure, getting rid of accumulated debris and
checking for leaks. SF6 Breakers count on sulfur hexafluoride gas to
quench the arc on their operation, so it’s paramount that the gas’s
integrity is maintained. - Oil Circuit Breakers (OCB) require consistent assessment and
replacement of the oil used. It’s essential to change the oil when it
becomes exceedingly contaminated. Furthermore, regular checks on the
physical condition of the circuit breaker, as well as cleaning and
adjusting it, will ensure smooth operations.
Remember, it is necessary to refer to your equipment manufacturer’s
guidelines for site-specific and equipment-specific maintenance tasks.
These tasks can be technical and may require assistance from trained
professionals to avoid mishandling and accidental damage.
Key Steps in Circuit
Breaker Maintenance
Visual Inspection
Visual inspection is the initial and one of the most critical steps
in circuit breaker maintenance. It involves gauging the physical
conditions of the unit in an attempt to identify any visible signs of
wear or damage that could impair its functionality.
This process starts by visually checking for any external damage on
the breaker, such as cracks, deformations or discolorations on the
casing, which could be a consequence of overheating, physical impact or
day-to-day operational stress.
Next, inspect the condition of the connections. Loose or corroded
connections can cause overheating and potentially lead to faults in the
device, while burnt or pitted contacts imply arcing and high resistance
– significantly reducing breaker efficiency. Finally, observe the status
of the protective covers and seals; they play a vital role in protecting
internal components from dust, moisture and other damaging elements.
An advantage of visual inspection is that it does not require
advanced technical skills or special equipment, yet it can prevent many
potential problems by identifying and rectifying issues early. However,
it is important to note that some defects may be hidden and not visible
to the naked eye, reinforcing the need for the other steps in the
maintenance plan.
Consequently, never underestimate the importance of a thorough visual
inspection. It is a simple yet effective preventive measure that can
save you from costly repairs and hazardous situations. Remember, it is
always safer and less costly to prevent a problem than to solve one.
Cleaning
Proper cleaning is a significant part of the circuit breaker
maintenance process. Over time, dust and grime can accumulate inside the
circuit breaker and may cause malfunctioning. This step primarily
focuses on the removal of these unwanted elements, especially from the
breaker’s contact surfaces.
The cleaning process involves unplugging the device from the power
source and then using a blower or a vacuum cleaner to remove dust and
dirt particles. A soft brush is also helpful in cleaning the areas
gently without causing damage.
More stubborn dirt can be addressed using clean and lint-free rags
dampened with high-grade isopropyl alcohol. However, one must be
cautious to prevent the alcohol from dripping into other components.
It’s essential to let the breaker air dry completely before turning the
power supply back on to avoid any electrical accidents.
Finally, the cleaning task isn’t only limited to the breaker’s
interior. It’s equally crucial to clean the exterior part of the breaker
including control panel, display board, handles and cover. A simple wipe
with a damp cloth can get the job done effectively.
Remember, safety is paramount during this process. Therefore, one
should wear insulating gloves and safety glasses to protect against
potential hazards.
Mechanical checks/test
Mechanical checks and tests form a vital part of circuit breaker
maintenance. They aim to ensure the efficient working of all the
mechanical components, which can wear over time due to their moving
nature.
The general procedure involves a thorough inspection of the circuit
breaker for any visible mechanical faults. Regular issues to look out
for include damaged parts, loose bolts, and wear and tear signs such as
rust or corrosion on the components. Additional physical features like
the breaker’s housing, insulator condition, and total alignment should
also fall under your inspection. All these should be in a good state to
allow for optimal function.
Next, confirm the tripping mechanisms’ full functionality to provide
safety in case of circuit overload. Also, verify that the racking
mechanism functions efficiently, ensuring the breaker moves smoothly
between connected, disconnected, and test positions.
Moreover, the spring operating mechanism needs to be examined.
Inspecting this involves looking at the cocking and trip-free
mechanisms, ensure the tripping devices operate as expected, and
unobstructed moving parts and linkages. The application of force on the
circuit breaker should be followed by an instant response, which acts as
proof of a robust mechanical system.
Lastly, a mechanical check should involve a timing test. A timing
test checks the circuit breaker’s operating speed, ensuring the contacts
separate at the appropriate time, reducing the risk of an electrical
fault. A delay can cause severe damage to the system.
During these tests, if any irregularities, inconsistencies or
malfunctions are detected, they should be rectified immediately to
prevent failure of the circuit breaker and ensure the safe operation of
electrical circuits. Remember, mechanical checks are only a part of the
comprehensive maintenance routine, but they play a significant role in
preventing catastrophic system failures.
Electrical check/test
The electrical check or test is a pivotal step in circuit breaker
maintenance. This step assesses the ability of the breaker to perform
its main responsibility: cut off electrical flow when necessary. It also
ensures that all protective devices inside the circuit breaker are
correctly calibrated and functional.
Checking the voltage is usually the initial phase of the electrical
check. The voltage readings should be within the manufacturer’s
prescribed limits at all reference points. Deviation from these limits
could point to an underlying issue needing immediate attention such as a
potential short-circuit or insulation failure.
Another significant aspect is testing for contact resistance.
Excessive contact resistance can lead to overheating, circuit failure
and, in severe cases, fires. A micro-ohmmeter is used for this check,
which applies a low voltage high DC current and measures resistance in
micro-ohms.
Next, timing tests are also carried out. Different types of timing
tests like close-open, open-close, close-open-close, etc., are performed
to verify the breaker’s mechanical and electrical operating times.
Special timing devices are used to measure these intuitive periods and
compare them with standard values.
Finally, verification tests for protection accessories such as shunt
trips and under-voltage releases should be performed. These tests ensure
all protective elements within the breaker are operable and offer the
required protection level.
All these tests should be conducted while adhering to safety
guidelines, using the right equipment and trained personnel, as the
process involves high electrical quantities. Results from these tests
can provide meaningful information on required remedial or preventive
actions, ensuring the breaker’s optimal functioning and prolonging its
lifespan.
Lubrication
Lubrication is a critical part of the circuit breaker maintenance
routine. Over time, friction can lead to the wear and tear of moving
parts within the breaker mechanism, reducing its efficiency and
potentially leading to failure. To prevent this, the appropriate
lubrication must be applied.
The type of lubricant used will depend on the manufacturer’s
recommendations, as well as the type and design of the breaker. Often, a
light machine oil or white lithium grease is recommended. Some compact,
low-voltage models may require a silicone-based lubricant.
Applying the lubricant is a careful process. Too little may leave
some parts unprotected, while too much can attract and accumulate dust,
debris, and other contaminants that can harm the performance of the
circuit breaker. Ensure to lubricate pivotal points where metal-to-metal
contact occurs and carefully wipe off any excess to prevent dirt
accumulation.
Following proper lubrication guidelines will not only ensure the long
life of the circuit breaker but also enhance its operational efficiency,
thereby upholding electrical safety standards in your home or business.
Keep in mind that lubrication should be done on a regular basis,
according to the manufacturer’s guidelines and the work environment in
which the breaker operates.
For high-voltage circuit breakers, high-grade lubricants are often
required and the procedure may be more complex. If you’re unsure about
any aspect of the lubrication process, it’s always best to consult
professional services to avoid causing any damage to the breaker or
creating a safety hazard.
Circuit Breaker Servicing
Period
Defining Servicing Period
The servicing period for a circuit breaker is the interval of time
recommended between successive maintenance routines. It represents the
span during which your circuit breaker can operate at optimal
functionality, given that it has been installed correctly and under
normal operating conditions. The duration of the servicing period varies
depending on the type of breaker and the environmental conditions in
which it operates. However, it is of importance to note that the
servicing period is not definitive as it may need to be adjusted based
on factors such as frequent usage or the presence of harsh environmental
conditions.
Factors Influencing
Servicing Period
Several factors play a pivotal role in determining the servicing
period of circuit breakers. First, the frequency of use influences the
maintenance schedule. Devices that undergo heavy usage require more
frequent attention compared to those used less frequently.
Second, the environment where the circuit breaker is situated also
affects the service span. For instance, circuit breakers in dusty or
corrosive environments tend to degrade faster, hence needing regular
maintenance.
Third, age and condition of the circuit breaker also come into play.
Older circuit breakers or those showing signs of wear and tear often
call for routine checks and servicing.
Lastly, manufacturers’ recommendations significantly influence the
servicing period. Manufacturers usually provide a guideline indicating
when specific maintenance tasks need to be performed, and it’s essential
to adhere to these instructions.
All these factors combined help to devise a suitable maintenance
schedule for circuit breakers, ensuring their efficiency and long
life.
Regularity
of Maintenance based on Use and Environment
The frequency of circuit breaker maintenance is intrinsically related
to its use and environment. Breakers that are operated frequently or are
situated in harsh environmental conditions will inevitably require more
regular checks and maintenance.
In high-usage scenarios, like industrial plants or commercial
facilities, the chance of wear and tear on the circuit breaker is
considerably higher. Hence, these breakers should be checked at least
twice a year, if not more, depending on the degree of use. On the other
hand, residential breakers may only require annual or bi-annual
inspections.
Environmental conditions also play a significant role in determining
the maintenance schedule. Circuit breakers in humid, dusty, or corrosive
atmospheres, such as near coastal areas or factories, will require more
frequent attention. The corrosive influences can degrade mechanical
parts and electrical contacts, provoking malfunction or breakdowns.
However, even in favorable conditions, it’s advisable to carry out
maintenance at least annually to prevent unexpected issues and ensure
the ongoing safety and efficiency of the circuit breaker.
Safety
Procedures in Circuit Breaker Maintenance
Needed Safety Tools and
Equipment
Conducting maintenance on circuit breakers requires a certain level
of personal protective equipment (PPE) to ensure safety during the
procedure. The first essential item is safety glasses. These are crucial
for protecting your eyes from potential hazards like dust, debris, or
sparks that may occur while working.
Second, a pair of insulated electrical gloves is recommended. These
gloves are specifically designed to protect against electrical shocks.
Gloves should be properly rated for the maximum voltage of the equipment
you’re working on.
An electrical multimeter is another vital tool. It allows you to
measure voltage and verify that the circuit you are working on is
de-energized. Verifying zero energy is one of the essential steps before
beginning any work on electrical components.
Non-conductive tools such as insulated screwdrivers, pliers, and
wrenches should be in your tool kit. These tools are insulated to
prevent electricity from passing through them and causing a shock.
Finally, consider investing in a flame resistant (FR) clothing or
apron. In the unlikely event of an arc flash or short circuit, FR
clothing provides an extra layer of protection from possible fire.
These are the necessary safety equipment needed for circuit breaker
maintenance. Remember, your safety should always be a priority,
especially when dealing with electricity. Never attempt to perform any
maintenance without the proper PPE.
Essential Safety Rules

crucial safety rules. Circuit breakers can house lethal levels of
electricity, so turning off power is a must to avoid electrical
shock. - Use Personal Protective Equipment (PPE): Always wear appropriate
safety gear. This includes safety glasses, insulated gloves, and
protective footwear. Also, consider using arc-flash protective clothing
if required by code or employer. - Use Insulated Tools: Tools should be insulated and rated for
electrical work. Using the wrong tool can lead to accidents and
injuries. - Double Check: Always double-check to ensure that power is off
before you touch any electrical components. Use a voltage tester to
confirm. - Follow Lockout/Tagout Procedures: If you’re working in a
commercial or industrial setting, it’s vital to follow appropriate
lockout/tagout procedures. This includes disconnecting power sources and
marking them so everyone knows work is being done. - Never Assume: Just because a circuit is off or a wire appears
‘dead’ does not mean it’s safe to touch. Always use a tester to make
sure. - Understand the System: Do not attempt to work on a circuit
breaker unless you fully understand its working and details. If you’re
unsure about any aspect, consult a professional. - If in Doubt, Contact a Professional: While some maintenance tasks
can be done by capable homeowners or property managers, repairs or more
complex tasks should always be handled by a qualified
electrician. - Keep your Work Area Clean and Organised: This helps prevent
slips, trips and falls, and avoids making errors that could lead to
electrical accidents. - Stay Alert: Be fully aware of your surroundings and watch for any
potential hazards. Make sure to concentrate fully on the task at hand

significantly reduce the risk of electrical accidents and help ensure a
safe work environment.
Risks in Ignoring Safety
Measures
Ignoring safety measures during circuit breaker maintenance can lead
to severe consequences that range from mild to life-threatening. One of
the major risks is electrical shock, which can result in severe injury
or even fatality. In some cases, this could be caused by touching live
components unintentionally, especially when the power supply is not
properly disconnected before the commencement of the maintenance
process.
Another risk is fire or an explosion. Circuit breakers are designed
to prevent such occurrences by interrupting current flow once a fault is
detected. However, if the circuit breaker itself is not in good
condition due to lack of maintenance, it might fail to perform its
function, resulting in a fire or explosion.
A further significant risk is equipment damage. A poorly maintained
circuit breaker can cause extensive damage to itself and other connected
equipment in the event of a fault. This can lead to costly repairs or
replacements, which could be avoided with regular and proper
maintenance.
Last but certainly not least, inadequate safety measures can lead to
health hazards. Some types of circuit breakers, like the SF6 circuit
breaker, use sulfur hexafluoride gas, exposure to which is harmful to
human health. Without proper safety measures in place, such hazards can
greatly put maintenance personnel at risk.
In summary, though circuit breaker maintenance may seem
straightforward, it is a procedure that requires adherence to all safety
rules to guarantee personal safety and the longevity of your equipment.
