Air Circuit Breaker (ACB)

An Air Circuit Breaker (ACB) is a protective device used to protect electrical circuits from overloads, short circuits, and faults. ACBs are essential for ensuring safety, reducing risks of electrical fires, and preventing damage to equipment.

Yes, Delta ACBs come with optional Modbus, Profibus, and Zigbee communication modules for remote monitoring and real-time fault detection, allowing operators to keep track of the system's performance.

Total selectivity ensures that only the affected circuit trips during a fault, keeping the rest of the system operational. This minimizes downtime and reduces disruptions to critical operations.

The E3DLMD series is designed for lower ratings (up to 3200A), while the E4DLMD series is intended for higher ratings (up to 6300A), offering more flexibility based on the electrical load and application requirements.

The Delta ACB range features a modular design with fixed and draw-out options, available in 3-pole and 4-pole versions. It supports accessories like shunt trip coils and under-voltage releases for flexible system customization.
