The Air Circuit Breaker (ACB) is a high-performance switching and protection device designed for low-voltage industrial power systems. Built for main distribution panels, generator protection, and large industrial loads, an ACB provides accurate overload, short-circuit, and ground fault protection for critical electrical circuits.
Using air as the arc extinguishing medium, ACBs are engineered for high breaking capacities and frequent operation cycles. They are equipped with electronic trip units, adjustable settings, and manual or motorized operation for remote monitoring and automation integration.
Ideal for applications in power plants, factories, large commercial buildings, and data centers, ACBs ensure safe disconnection during electrical faults while maintaining operational continuity.
