Use and scope of application

NMG1 (NMWG) series load disconnecting switch is a new type of replacement product developed by our company. The products are derived from cabinet operation, post-board wiring, NMG1 (NMWG) isolating switch fuse group, automatic power conversion load disconnecting switch, etc. and series of products are widely used in the transmission, distribution and automation systems of construction, power, chemical and other industries. .

NMG1 (NMWG) series load disconnecting switch is suitable for AC 50Hz, rated current 100A-1600A (1000A or above is only suitable for electrical isolation), rated insulation voltage to 800V and rated working voltage to 690V and below, DC rated working voltage 380V In the following distribution or motor networks, it is used as an infrequent connection, disconnection circuit and line isolation.

There are also NMGR1 and NMWGR isolation switch fuse sets in the same series. Please contact us for details.

Model meaning

Note: 

1. NMG1 and NMWG have the same shape and size. NMG1 is a pure gray resin material, and NMWG is the same marble pattern as Wangao WG. NMG1 or NMWG can choose one model, but not NMG1 (NMWG)!

Product Features

◆The product is novel, beautiful and practical;

◆Small size, can be carried out from time to time, sub-operation (800A and below)

◆A variety of wiring forms, the protection level reaches P30, safe and reliable use;

◆Associate double breakpoints, the isolation distance is large,

◆Directly display the contact points,

◆Spring energy storage mechanism, to achieve quick pass, break:

◆The iron nut is locked to improve the mechanical strength of the terminal:

◆The arc-extinguishing system has an unfair design for the arc channel, which improves the breaking capacity, and reduces the carbonization of the arc of the arc, reducing the leakage current.

◆It has three poles, four poles, inner and outer cabinets, and front and rear panel wiring.
