MDmax Low Voltage Switchgear

ABB authorized switchgear.

Suitable for three-phase AC 50, (60)Hz, rated working voltage and rated insulation voltage of 400V, 690V, rated current of 6300A and below three-phase four-wire system and three-phase five-wire system power system, widely used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, terminals and radio and television communication centers. It is used as PC and motor control center MCC in power distribution for power generation, transmission and distribution, power conversion and power consumption.

Introduction

The automation process of industrial users is becoming more and more complex, the social cost of unexpected power outages of infrastructure is becoming higher and higher, and different loads and working conditions will also affect the operation of low-voltage switchgear, causing power supply failures. How do you have less failure, less downtime, and as much reliable power as possible?
A new generation of MDmax digital low-voltage switchgear, with the concept of the system, and the integration of digital intelligent technology, so that the traditional switchgear technology to keep pace with The Times, become a smart member of the Internet of Things; It can be widely used in various industries, infrastructure, rail transit, high-end buildings and other fields to provide users with digital solutions and services to ensure safer and more reliable power supply.
