In the intricate world of electrical systems, the Air-operated Circuit Breaker (ACB) stands out as a crucial component, ensuring the safety and reliability of power distribution networks. Also known as a fixed-mounted circuit breaker, the ACB breaker performs a vital function in controlling and protecting electrical circuits from damage caused by overloads, short circuits, and other abnormal conditions.

    The ACB breaker's design is unique, with all its components, including the contact system, trip unit, and protective devices, housed within an insulated metal frame. This robust construction ensures its durability and ability to withstand the demands of high-voltage and high-current applications. The breaker's capacity ranges from 200 to 4000 amperes, making it suitable for use as the main switch in low-voltage distribution systems, protecting incoming lines, bus couplings, and other critical, heavily loaded trunk circuits.
