In the realm of electrical distribution systems, the Air Circuit Breaker (ACB) stands tall as a crucial component. Also known as the air circuit breaker, it is a vital safety device that ensures the smooth and safe flow of electricity. This article delves into the workings, importance, and applications of the ACB breaker.

The Working Principle of ACB Breaker

ACB breakers, much like other circuit breakers, function to interrupt the flow of current in case of an electrical fault. When a fault such as a short circuit or overload occurs, the ACB breaker trips, disconnecting the faulty circuit from the power source. This action prevents damage to equipment and reduces the risk of fire. ACB breakers differ from other types of circuit breakers in their design and construction. They use compressed air to cool the arc formed during the interruption of current. This cooling action extends the lifespan of the breaker and allows for faster, more reliable operation.
