Product Description

 

Product Description

 

Product description:
ACB (Air Circuit Breaker) is a high-performance low-voltage circuit breaker, with representative models including MT/NT and MVS series, covering rated currents of 630A~6300A, with a breaking capacity of up to 150kA, suitable for industrial, commercial, and energy distribution systems.

Core features:
Intelligence: Built in Micrologic release, supports real-time monitoring (current, voltage, fault recording) and remote control, compatible with EcoStruxure platform.

High reliability: modular design, optional electronic/thermal magnetic protection, with a lifespan of tens of thousands of operations.

Comprehensive protection: Provides overload, short circuit, and ground fault protection, and supports selective coordination.

Flexible Expansion: Communication modules (Modbus, Ethernet) and auxiliary contacts can be installed.


 

Working principle:

The air circuit breaker monitors the current in the circuit in real-time through a current transformer. And transmit the current signal to the intelligent controller.

After the intelligent controller detects the abnormal current, it will disconnect the contacts inside the circuit breaker and cut off the circuit
