1. General  

1.1 MNS modularized, multifunctional low voltage drawble switchgear, which is applicable to metallurgy, petroleum, chemical industrial, industrial and mining enterprises and all the situations high reliable low voltage system, distribution system and motor control system are needed. 

 

1.2 The structure of the switchgear panel body has high flexibility.

 

The elements of many types and specifications can be installed in the cabinet according to your requirements or different using situations.

 

The polytype feeder units can be installed in the same list of the cabinet or in the same cabinet according to different electricity equipments. E.g.: the feeding loop and the motor control loop can be wired together.

 

1.3 WMNS series low voltage switchgear panel can meet your needs completely. It is applicable to all low voltage systems of the current 4000A or below.

 

1.4 WMNS can supply you high level reliability and safety. Its humanized design enhances the protection both for the human body and for the equipments.

 

1.5 WMNS is full assembly structure, whose special sectional material and the connection mode as well as the compatibility with the elements can meet the requirements from the working period and the continuity of the power supply.

 

1.6 Execution standard:IEC60439-1GB7251.1.

 

2)suitable place  

 

1: all places where required high reliability and safe power distribution and motor  control.
