Circuit Breakers

A circuit breaker is an automatically operated electric switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. 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.

1110-F212-P1M1-13A Application Field and Working Principle

1110-F212-P1M1-13A is a kind of circuit breaker produced by the Surnova Electric Company, mainly used for overload and short circuit protection of AC 400V, 50/60Hz, three-phase four-wire systems, and is suitable for lighting distribution in railways and bus transportation. Its rated current is 100A, rated short-circuit breaking capacity is 6kA and rated operating frequency is 300 times/h.

The 1110-F212-P1M1-13A circuit breaker is usually equipped with three-phase AC auxiliaries such as release and load switches. It has a trip indicator function, providing good visual visuals, which can help improve the safety and reliability of power distribution. A device that is especially suitable for railway lighting distribution.

Working Principle

The 1110-F212-P1M1-13A circuit breaker is mainly composed of a circuit breaker contact system, arc extinguishing chamber and operating mechanism. The current carrying contacts are mounted in a symmetrical arrangement in a separate contact group.

The 1110-F212-P1M1-13A circuit breaker works when an overload current or short circuit current flows along the closed contact, the action of the electromagnetic attraction provided by the arcing contact will be instantly weakened and the current will be interrupted. Once the contact breaks, the arcing current flowing between the contacts is extinguished due to the installation of the arc extinguisher.

This circuit breaker is also equipped with an overload protection device. When an overload current is detected, an electromagnetic attracting force caused by the saturation current of the bimetal will pull the circuit breaker trip lever downward and the contact will be opened.

Conclusion

The 1110-F212-P1M1-13A circuit breaker is a versatile and powerful device for both overload and short circuit protection. It is especially suitable for railway lighting distribution as it provides good visual visuals, as well as excellent current detection and interruption functions.
