An Air Circuit Breaker (ACB) is a heavy-duty electrical protection device used to protect low-voltage electrical power distribution systems from overloads, short circuits, and earth faults. It uses air as the arc extinguishing medium, making it reliable, safe, and easy to maintain. ACBs are commonly installed in main distribution panels (MDP), low-voltage switchboards, industrial plants, commercial buildings, data centers, and power stations.
Air Circuit Breaker (ACB)
- High current ratings from 800A to 10,000A
- Voltage rating up to 1000V AC
- High breaking capacity for fault protection
- Adjustable electronic trip unit
- Protection against overload, short circuit, and earth fault
- Manual or motorized operation
- Fixed and draw-out versions available
- Long service life with low maintenance requirements
Molded Case Circuit Breakers (MCCBs) are low-voltage protection devices designed to safeguard electrical circuits against overloads, short circuits, and earth faults. They provide reliable protection for industrial, commercial, and residential electrical systems and are widely used in distribution panels and motor control centers.
