Product Profile

◆Product Summary

MNS low Voltage withdrawable type switchgear is used for conversion,distribution and control of electrical energy of powerdistribution equipment of AC 50~60Hz,400V.It is mainly used in airports,power plants,substations,petrochemical plants,metallurgicplants,steel plants,transportation energy,light textile and residential districts,high-rise buildings,etc.The switchgear conforms to

IEC439,GB/T7251.1 and other professional standard.It uses standard module design,and it can respectively form standard units-suchas protection,operation,conversion,control,regulation,determination and indication.Over 200 types of assembly parts can formframe structures of different schemes,and form fixed separation or drawer units.The users can select assemblies arbitrarilyaccording their demands.

◆Product Features

1.The operation of drawer is combined with the control handle.It has simplified the operation,and overcome the shortcomings that

2.The MCC unit has a lot of combinations,with compact structure.The cabinet body can share busbars,which are arranged back toback.A maximum of 36 loops can be assembled for each cabinet.the operation of traditional MNS cabinet is complicated.

3.The cabinet body can be arranged back to back or against the wall,which can save installation space.

4.All of the standard components are selected to facilitate the design of engineering designers.

5.The whole series is standardized,the structure is versatile and the assembly is flexible.

6.The combination performance is stable and the earth continuity is good.

7.The device has a high continuity and reliability.

8.The product has passed the aseismic,salt fog and EMC electromagnetic compatibility test,and the operation is safe and reliable.
