MNS low voltage withdrawable switchgear

Product Overview

The cabinet structure adopted by MNS is highly flexible.

According to your needs or different usage occasions, various types and specifications of components can be installed in the cabinet; according to different electrical equipment, various types of feed units can be installed.

In the same row of cabinets or the same cabinet, for example, the feeder circuit and the motor control circuit can be mixed together.

MMNS is a full range of low voltage switchgear that can meet your full office needs. It is suitable for all low voltage systems below 4000A.

MNS can provide high level of reliability and safety. The humanized design strengthens the protection required for personal and equipment safety.

MNS is a fully assembled structure. Its unique profile structure and connection method as well as compatibility with various components can meet the requirements of demanding construction periods and power supply continuity.

Implementation standards: IEC439, GB7251.1.

Key Features

1.In order to facilitate the installation and on-site construction of the equipment, a dedicated cable channel is provided in the distribution cabinet, and corresponding cable fixings are attached.

2.Each position of the drawer unit is accurately positioned and clearly indicated, and each position can be locked with up to 3 padlocks.

3.Special profile structure and connection method ensure the strength of the cabinet.

4.The drawer unit uses contact wires to directly connect with the "L'-shaped vertical busbar, which is simple and reliable.

5.The unique three-section guide rail makes the drawer more flexible and convenient to enter and exit, and the internal components and wiring can be inspected, maintained or replaced without the drawer unit leaving the cabinet.
