MNS

The MNS low-voltage draw-out switchgear is developed by our company after referring to and comprehensively improving the MNS low-voltage switchgear of ABB Company in Switzerland. It is a relatively complete low-voltage draw-out switchgear.

This product is composed of standardized and serialized modules, and the drawers are equipped with reliable mechanical interlock devices, making it safer and more reliable for users during use.

This switchgear is suitable for three-phase five-ire power supply systems with an alternating current of 50 (60) Hz, a rated operating voltage of 1kV and below,and a rated current of 6300A and below.It can be used in power plants, substations, industrial and mining enterprises, buildings and hotels, airports, docks, and communication centers such as radio and television.

It is used for the control of power generation, power transmission and distribution,power conversion and power consumption equipment, and the main busbar is subject to reactive power compensation through the capacitor compensation cabinet.

There are five sizes, all designed with a modularstructure at a height of 8E (200mm),and the effective installation height of the components is 1800mm, making the oveall layout of the cabinet more reasonable and beautiful.

8E/4: Height 200xWidth 150xDepth 400.Four drawer units are combined in parallel within the height space.

8E/2: Height 200xWidth 300xDepth 400.Two drawer units are combined in parallel within the height space.

BE: Height 200xWidth 600xDepth 400.One drawer unit is assembled within the height space.

16E: Height 400xWidth 600xDepth 400.One drawer unit is assembled within the height space.

24E: Height 600xWidth 600xDepth 400. One drawer unit is assembled within the 24E (600mm)height space.

Type description

Normal service condition

The ambient air temperature shall not be higher than +40℃ and not lower than -5℃, and the average temperature within 24 hours shall not be higher than +35℃. When these limits are exceeded, the capacity shall be derated for operation according to the actual situation.

It is for indoor use, and the altitude of the installation locatin shall not exceed 2000m.

The relative humidity of the ambient air shall not exceed 50% when the maximum temperature is +40℃. At lower temperatures, a higher relative humidity is allowed. For example, it is 90% at +20°℃. The influence of occasional condensation caused by temperature changes should be taken into account.

When the device is installed, the inclination from the vertical plane shall not exceed 5°, and the entire group of cabinet rows shall be relatively flat.The device shall be installed in a place without severe vibration and impact, and where the electrical components will not be subject to undue corrosion.
