Product Overview

MNS is a modular and multifunctional low-voltage distribution cabinet. Applied to all low voltage systems that require high reliability in metallurgy, petroleum, chemical, industrial and mining enterprises, and infrastructure fields: distribution and motor control systems.

The cabinet structure used by MNS has a high degree of flexibility.

According to your needs or different usage scenarios, various types and specifications of components can be installed in the cabinet; According to different electrical equipment, multiple types of feeding units can be installed in the same cabinet or cabinet. For example, the feeding circuit and the motor control circuit can be mixed together.

MNS is a full range of low-voltage switchgear that can meet your comprehensive needs. Suitable for all low-voltage systems below 4000A. MNS can provide a high level of reliability and safety. Humanized design enhances the protection required for personal and equipment safety. MNS is a fully assembled structure, with its unique profile structure and connection method, as well as compatibility with various components, which can meet the requirements of demanding construction periods and power supply continuity.

Product functional features

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

● The drawer unit has accurate positioning and clear indication at each position, and can be locked with up to 3 padlocks at each position.

● The special profile structure and connection method ensure the strength of the cabinet.

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

● The unique 3-section guide rail makes drawer entry and exit more flexible and convenient, and allows for inspection, maintenance, or replacement of internal components and wiring without disconnecting the drawer unit from the cabinet.
