The function of a circuit breaker in a protection relay is to safeguard the electrical system from overloads, short circuits, and other abnormal conditions. It automatically interrupts the electrical flow based on the signal received from the relay, ensuring the protection of the system.
Circuit Breaker
A circuit breaker is an automatic electrical switch designed to protect the electrical system from overloads, short circuits, and other abnormal conditions. This device immediately interrupts the electrical flow when any danger or abnormal situation arises, keeping equipment and the system safe. The circuit breaker can be reset manually or automatically, allowing the system to be restarted. It is an essential safety device used in homes, industrial units, and power grids. Circuit breakers play a crucial role in maintaining safe and reliable electricity supply.
Function of Circuit Breaker
A circuit breaker is a safety device whose main function is to protect an electrical circuit from overload, short circuit, or any other abnormal electrical condition. Whenever the current exceeds the specified limit or a fault occurs in the circuit, the circuit breaker automatically interrupts (trips) the flow of electricity.
This prevents damage to the equipment and the entire electrical system. After the issue is resolved, the circuit breaker can be manually turned on (reset) again.

Function of Circuit Breaker in Relation to Protection Relay
The protection relay and circuit breaker work together to ensure the safety of the electrical system.
When an overload, short circuit, or any other abnormal condition occurs in the electrical system, the protection relay first detects the fault and immediately sends a trip signal to the circuit breaker.
Upon receiving the signal, the circuit breaker operates and interrupts the flow of electricity to prevent any kind of damage to the system or equipment. How does a protection relay solve problems related to overload? Click here https://www.nsengineers.co.in/blogDetails/28 to learn more! ⚡
Conclusion
In conclusion, the protection relay and circuit breaker together form an essential part of the electrical protection system. The relay acts as a sensing and signalling device, while the circuit breaker performs the actual operation of disconnecting the faulty section. Their coordinated functioning ensures the safety, reliability, and smooth operation of the entire power system by preventing damage caused by faults like overloads or short circuits.
