Product Description
MNS type low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is developed by our company after referring to the MNS series low-voltage switchgear of ABB company in Switzerland and comprehensive improvement, and is currently the most advanced low-voltage withdrawable switchgear in China. The products are all made up of standardized, series of modules, and the drawers have reliable mechanical interlocks, making them safer and more reliable for users to use.
This switch cabinet is suitable for AC 50 (60) Hz, rated working voltage 400V, 660V, rated current 5000A and below three-phase five-wire power system, can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks and radio and television and other communication centers, as power generation, transmission and distribution, power conversion and power consumption equipment control, and through the capacitance compensation cabinet to the founder bus reactive power compensation. Comply with the national standard: GB7251.1 "low-voltage switchgear" IEC60439 "low-voltage switchgear and control equipment"
