Introduction to Circuit Breakers
A circuit breaker is an essential electrical safety device designed to protect an electrical circuit from damage caused by overload or short – circuit. When an abnormal current, such as excessive current due to overloading or a sudden short – circuit, flows through a circuit, the circuit breaker automatically interrupts the flow of electricity. This helps prevent overheating of wires, which could lead to fires, and damage to electrical equipment. Circuit breakers are used in a wide range of applications, from residential electrical panels to large – scale industrial and commercial electrical systems. Circuit Breaker
