MNS type low-voltage draw-out switch cabinet (hereinafter referred to as switch cabinet) is developed by our company after referring to the MNS series low-voltage switch cabinet of Company of Switzerland and making comprehensive improvement. It is currently a relatively advanced lowvoltage draw-out switch equipment in China. This product is composed of standardized and series modules, and the drawer has reliable mechanical interlocking device, which makes users safer and more reliable in use. 

The switch cabinet is suitable for a three-phase five-wire power supply system with AC 50(60)Hz, rated working voltage 400V, 660V, rated current 5000A and below. It can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks, radio and television and other communication centers to control power generation, transmission and distribution, power conversion and power consumption equipment, and perform reactive power compensation on its main bus through a capacitance compensation cabinet. Comply with national standards: GB7251.1 《Low Voltage Complete Switchgear》 IEC60439 《Low Voltage Complete Switchgear and Control Equipment》
