ACB (Air Circuit Breaker)
ACB (Air Circuit Breaker) is a high-capacity protective device used to protect electrical circuits, transformers, and distribution systems from overcurrent, short circuits, and electrical faults. Unlike MCCBs, ACBs are suitable for higher voltage and current ratings, making them ideal for industrial and commercial power distribution systems. They use air as the arc quenching medium and provide reliable switching, protection, and control for medium-voltage installations.
