How Do Air Circuit Breakers Improve Power Systems?

An air circuit breaker (ACB) is a type of circuit breaker that uses air as the medium to extinguish the arc formed during circuit interruption. The primary purpose of an air circuit breaker is to protect electrical circuits and equipment from overloads, short circuits, and faults. When excessive current flows through the circuit, the ACB trips, interrupting the flow of electricity to prevent damage to the system and ensure safety. They offer reliable performance, easy maintenance, and the capability to handle large currents, making them essential components for maintaining the stability and safety of electrical installations.
