[0002] A circuit breaker, also known as an automatic switch or air switch, is an electrical device that plays a key protective role in a circuit. Its main function is to quickly cut off the circuit when a short circuit, overload or undervoltage occurs in the circuit to prevent damage to electrical equipment, prevent electrical fires, and protect circuit safety. When selecting a suitable circuit breaker, you need to consider the circuit's rated voltage, rated current, short-circuit breaking capacity, and whether specific protection functions are required.
