MNS type low voltage drawer type switchgear is low voltage draw-out type switchgear. The product is composed of standardized, series of modules, and the drawer has a reliable mechanical interlocking device, so that the user is stable and reliable in use.

This switchgear is suitable for 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, building hotels, airports, docks, radio and television and other communication centers as power generation, power transmission and distribution, power conversion and power consumption equipment control, and reactive power compensation is carried out on its main bus through capacitance compensation cabinet. In line with national standards: GB7251.1 "low-voltage switchgear" IEC60439 "low-voltage switchgear and control equipment"

Use environment and scene

1. For indoor use, the altitude of the use point shall not exceed 2000m.

2. The ambient air temperature is not higher than 40 degrees and not lower than minus 5 degrees. And the average temperature within 24 hours shall not be higher than 35 degrees. When exceeding, the operation shall be reduced according to the actual situation.

3. The relative high temperature of the surrounding air is +40 degrees and not more than 50%, and a larger relative temperature is allowed at a lower temperature; if +20 degrees is 90%, consideration should be given to the influence of accidental condensation due to temperature changes.

4. When the device is installed, the inclination with the vertical plane shall not exceed 5 °, and the whole group of cabinets shall be relatively flat and conform to the (GBJ232-2) standard.

5, the device should be installed in the absence of severe vibration and impact and not enough to use electrical components should not be corroded.
