FAQs of Circuit Breaker
What is a circuit breaker?
A circuit breaker is an electrical device to automatically interrupt the current flow in a circuit when it detects an overload or short circuit. This protection mechanism prevents damage to electrical systems and reduces the risk of fires or equipment failure.
Circuit breakers function by opening their contacts to break the circuit when excessive current is detected. Once the fault is cleared, it can be reset to restore normal operation.
How does a circuit breaker work?
A circuit breaker functions as a safety device to protect electrical circuits from damage. It works through a combination of thermal and electromagnetic mechanisms:
- Thermal Mechanism: Inside the breaker, a bimetallic strip heats up when excessive current flows through the circuit. The strip bends due to the differing expansion rates of the metals, triggering the breaker to trip and open the circuit. This prevents overheating and potential damage.
- Electromagnetic Mechanism: In a short circuit, a rapid surge in current generates a strong electromagnetic field. This field pulls an armature to release a latch that opens the circuit breaker’s contacts, quickly interrupting the flow of electricity and protecting the system.
Once the fault is cleared, the circuit breaker can be reset manually or automatically to restore power.

How to replace a circuit breaker?
- Turn Off Power: Ensure the main power supply to the electrical panel is turned off to avoid electrical shock.
- Remove the Panel Cover: Use a screwdriver to carefully remove the panel cover and access the circuit breakers.
- Identify the Faulty Breaker: Locate the circuit breaker that needs replacing. It should be labeled for easy identification.
- Disconnect the Faulty Breaker: Unscrew the terminal screws or disconnect the wires attached to the faulty breaker. Remove the breaker from its slot.
- Install the New Breaker: Insert the new breaker into the slot, ensuring it fits securely. Connect the wires to the new breaker and tighten the terminal screws.
- Replace the Panel Cover: Reattach the panel cover and secure it with screws.
- Turn On Power: Restore power to the panel and test the new breaker to ensure it functions correctly.
