Circuit Breakers

Circuit breakers are resettable protective devices that automatically stop electrical flow when a circuit becomes overloaded, shorted, or otherwise unsafe. They help protect wiring, components, and systems from damage while reducing the risk of overheating and fire. Unlike fuses, circuit breakers can be reset after the fault is cleared, making them a reliable and reusable solution for circuit protection across a wide range of applications.
