Product Description
Product Overview
The MNS type low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is developed by our company based on the MNS series low-voltage switchgear of ABB Switzerland and further improved. It is currently one of the most advanced low-voltage withdrawable switchgears in China. This product is composed of standardized and serialized modules, and the drawers have reliable mechanical interlocking devices, making it safer and more reliable for users.
This switchgear is suitable for AC 50(60)Hz, rated insulation voltage and operating voltage of 380(400)V, 660V, rated current of 5000A and below three-phase five-wire power supply.
The system can be used in power plants, substations, industrial and mining enterprises, large buildings and hotels, airports, docks, and communication centers such as broadcasting and television, to control power generation, transmission and distribution, power conversion, and power consumption equipment, and to perform reactive power compensation on its main busbars through capacitor compensation cabinets.
