Heavy-Duty Power Protection for Large Electrical Systems
The Air Circuit Breaker ACB provides powerful protection for low-voltage electrical networks handling high current loads. It protects systems from overloads, short circuits, and earth faults while maintaining reliable power continuity in critical operations.
Moreover, ACBs use air as the arc extinguishing medium, which ensures safe interruption of fault currents without oil or gas. As a result, these breakers offer easy maintenance, high breaking capacity, and long service life. Industries, hospitals, malls, and manufacturing plants depend on ACBs for main incomer and outgoing feeder protection.
