Product Description

Product Description

MEX air circuit breaker, a new generation of products developed from the classic ME air circuit breaker series, inherits the advantages and application experience of ME air circuit breaker family, combined with the current digital power environment, upgraded with a new digital intelligent control unit. As a low-voltage air circuit breaker for worldwide application, it meets GB, IEC and UL standard requirements.

The entire series is divided into 3 frame current classes, rated from 400A to 6400A, offering 3-pole and 4-pole products with rated breaking capacity up to 150kA and rated voltage up to AC1150V. 

A new generation of intelligent control unit, using new technology to make the circuit breaker provide safer and more reliable circuit protection features a variety of electrical parameters measurement and display. It can be connected via Modbus, 4G, Bluetooth, NFC, plug and play bus, APP online monitoring and other ways to achieve interconnection with the circuit breaker. Bluetooth provides a safe way to operate the circuit breaker, improving the safety of field operation. NFC can also read the stored data in the case of power failure.
