Product Overview
MNS type low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is developed by our company with reference to the MNS series low-voltage switchgear of Swiss ABB and comprehensively improved, and it is the more advanced low-voltage withdrawable switchgear in China at present. The product is composed of standardized and series modules, and the drawer has reliable mechanical interlocking device, which makes the user safer and more reliable when using.
The switchgear is suitable for AC 50(60)Hz, rated voltage 400V, 660V, rated current 5000A and the following three-phase five-wire power supply system, and can be used in power plants, transformer substations, industrial and mining enterprises, buildings and hotels, airports, terminals and communication centers such as broadcasting and television, as a power generation, transmission and distribution, power conversion and control of power consuming equipment, and through the capacitor compensation cabinet to provide reactive power to the main busbar. The capacitor compensation cabinet is used for reactive power compensation of the main busbar. GB7251.1 Low-voltage switchgear IEC60439 Low-voltage switchgear and control equipment.
