Air Circuit Breakers (ACBs)

Air Circuit Breakers (ACBs)

An air circuit breaker is a type of electrical breaker used to protect electrical systems from damage due to overloading, short-circuiting, or other electrical faults. Unlike other types of circuit breakers, which use oil or other insulating fluids to quench an arc and interrupt the flow of electricity, an air circuit breaker uses air to interrupt the flow of electricity and isolate the fault.
