In modern electrical systems, ensuring the protection of circuits from overloads and faults is paramount. One of the most reliable devices for this purpose is the air circuit breaker (ACB). Operating at low and medium voltage levels, ACBs play a crucial role in safeguarding equipment and maintaining system stability.
What Is an Air Circuit Breaker?
An air circuit breaker is an electrical protection device designed to interrupt the flow of current in the event of an overload or short circuit. Unlike oil or gas circuit breakers, ACBs utilize air at atmospheric pressure as the arc-extinguishing medium. This design eliminates the risks associated with flammable substances and offers a safer alternative for circuit protection.
