Product Description

MNS removable mv metal-clad switchgear panel metal-clad removable

enclosed ac power power distribution equipment

 Product overview

1. MNS Low-voltage draw-out switchgear is assembled with modules in the factory and is

used in the powering system of AC 50-60Hz and rated working voltage under 660V.

2. MNS Switchgear is applied for power supply system, power plants, substations,

industrial mining enterprises, high buildings, airports, stations, terminals, etc, where use

AC of 50-60HZ and voltage of 660V, needing functions such as distribution, motors and

electrical equipment's control, start-up, lighting, power conversion, power factor correction.



3. MNS withdrawable switchgear is a low-voltage complete power distribution device ,suitable

to AC 50-60Hz, rated working voltage of 660V or below, rated current of 4000A and below,

power distribution, motor centralized control,power factor correction.


4. MNS withdrawable switchgear is used as a substation, feed or motor for low-voltage distribution

systems of 3P-3W or 3P-4W.

MNS withdrawable switchgear has increased its capacity and mechanical strength on the basis

of maintaining higher electrical performance, and has characteristics of advanced structure, perfect

appearance, high protection level, safety and reliability, and easy maintenance.
