About Circuit Breakers

Circuit breakers are essential safety devices used to automatically interrupt electrical flow in the event of an overload, short circuit, or fault condition. Unlike fuses, circuit breakers can be reset after tripping, making them reusable and convenient. Available in various types such as thermal, magnetic, and hydraulic-magnetic, circuit breakers are crucial for protecting wiring, equipment, and maintaining system integrity.
