Key Features

Why Engineers Choose MNS

Datasheet-backed advantages for low-voltage distribution rooms where uptime and flexibility matter.

📤

Withdrawable Drawer Units

Functional units — protection, operation, transfer, control, regulation, measurement and indication — rack in and out as standardized drawers for maintenance without shutting down adjacent feeders.

🧱

25mm Modular Design

C-type bar-section framework on a 25mm modulus, with over 200 standard components able to form different cabinet-frame and drawer-unit combinations.

🧯

High-Strength Flame-Retardant Components

Large use of high-strength, flame-retardant engineering plastic parts strengthens the protective safety performance of the assembly.

🌊

Special-Environment Capable

Beyond standard indoor duty, MNS can be specially treated for marine oil-drilling platforms and nuclear power stations under a separate technical agreement.

FAQ

What Engineers Ask About MNS

Datasheet-driven answers for procurement teams and switchgear designers.

What voltage and current range does MNS cover?

MNS is rated for 380V and 660V working voltage (660V/1000V insulation voltage), AC 50Hz. Horizontal busbar rated current spans 630–5000A, and vertical busbar rated current spans 800–2000A.

Is MNS a withdrawable or fixed-type switchgear?

MNS is a withdrawable (drawer-type) switchgear. Functional units are mounted on drawers that can be racked out for maintenance without de-energizing neighboring feeders. For a fixed-type, bolted-in alternative, see the GGD product line.

What is the module design basis of MNS?

MNS cabinet and drawer dimensions follow a 25mm modulus, consulted from the Switzerland ABB MNS series low-voltage switchgear design and manufactured with standard modules for protection, operation, transfer, control, regulation, measurement and indication units.

What protection degree does MNS carry?

The enclosure is available in IP30 or IP40 protection grades, selected to match the installation environment.

Can MNS be used in harsh or special environments?

Beyond general indoor use, MNS can be specially treated for use on marine oil-drilling platforms and in nuclear power stations, in addition to standard mining, commercial building and municipal low-voltage distribution applications.

What is the outline dimension of a standard MNS cabinet?

Standard outline dimension (H × W × D) is 2200 × 600(800,1000) × 800(1000) mm, allowing width and depth to be selected to match the functional unit and drawer configuration required.
