MNS-TH Low Voltage Draw-out Switchgear

MNS-TH Low Voltage Draw-out Switchgear

Description
The MNS-TH low voltage withdrawable switchgear adopts current advanced modularized assembled structure. Operated from the front or rear side, this product can be widely used in various low voltage power supply and distribution systems in the airport, hospital, substation, power plant, industrial and mining enterprises, and other places. The maximum capacity of the transformer that can be configured is up to 2500 KVA.

Features
1. The main structure is formed by section steel or aluminum coated zinc plate. It is fully assembled.

2. Function rooms are separated from each other. There are functional unit room, bus room, and cable room. These rooms are relatively independent in function.

3. The horizontal main bus is mounted on the rear of the cabinet to enhance the bus's ability to resist electrodynamic force. The horizontal main bus can also be mounted on the cabinet top.

4. The MNS-TH low voltage withdrawable switchgear can be designed to have 1/4 drawer unit and each drawer unit is equipped with mechanical interlock.

5. Adopting high strength flame retardant engineering plastics, our product has high safety protection performance.
