Air Circuit Breakers (ACBs) are crucial devices in electrical systems, ensuring safety and efficiency by protecting circuits from overloads and short circuits. In this article, we delve into the functionalities, advantages, and applications of ACB breakers, which play a vital role in maintaining the integrity of electrical installations.

    An ACB is an electrical protection device designed to interrupt the flow of current in a circuit when it detects an abnormal condition such as an overload or short circuit. Unlike fuses, which need to be replaced after operation, ACBs can be reset and reused, making them a cost-effective solution for circuit protection. They operate by using an air gap to interrupt the electrical flow, hence the name "air circuit breaker."
