Air Circuit Breaker

An Air Circuit Breaker (ACB) is a high-capacity electrical protection device designed to safeguard low-voltage circuits and equipment from faults such as overload, short circuit, and ground faults. It operates using air as the arc extinguishing medium, ensuring safe interruption of high fault currents in industrial and commercial power distribution systems.

ACBs are widely used in main switchboards, power distribution panels, and generator systems where high current ratings and reliable protection are essential. They provide manual or motorized operation, adjustable trip settings, and easy maintenance, making them suitable for demanding electrical environments.

Modern ACBs also include electronic protection relays, enabling precise monitoring, fault diagnosis, and coordination with other circuit breakers for enhanced system safety and performance.
