The MNS low-voltage withdrawable switchgear (hereinafter referred to as the switchgear) is developed by our company with reference to the MNS series low-voltage switchgear of ABB in Switzerland and comprehensive improvements. It is currently one of the more advanced low-voltage withdrawable switchgear equipment in China. This product is composed of standardized and series of modules, and the drawers have reliable mechanical interlocking devices, making it safer and more reliable for users to use.
This switchgear is suitable for AC 50 (60) Hz, rated operating voltage 400V, 660V. A three-phase five wire power supply system with a rated current of 5000A or below can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks, and communication centers such as broadcasting and television to control power generation, transmission and distribution, energy conversion, and energy consumption equipment. The main busbar is compensated for reactive power through a capacitor compensation cabinet.





1.Modular & Integrated Structure
Adopts assembled frame structure with high strength, good rigidity and standard modular design. Units are highly interchangeable, convenient for assembly, maintenance and capacity expansion.
2.Compartmentalized Design
Equipped with independent compartments for main busbar, functional units and cables, effectively preventing fault spread, electric arc impact and short-circuit cross-interference.
3.Safe Three-position Mechanism
Drawer units have clear connect / test / disconnect positions with reliable mechanical interlocking, preventing misoperation and live withdrawal, ensuring personal and equipment safety.
4.High Electrical Performance
Excellent short-time withstand current and peak withstand current capability. Low temperature rise, low contact resistance, high insulation level, suitable for stable operation under heavy load.
5.Strong Environmental Adaptability
Suitable for high temperature, high humidity and salt-spray environments in Southeast Asia. Cabinet with anti-corrosion coating; busbars tinned or silver-plated for oxidation resistance.
6.Flexible Configuration & Wide Application
Can be assembled into power center (PC) and motor control center (MCC). Supports various functional units such as incoming, outgoing, coupling, metering and compensation.
7.High Protection & Reliability
Standard protection degree up to IP30/IP40, customizable to IP54 for outdoor or coastal applications. Stable performance, long service life and low failure rate.
8.Wide Compatibility
Compatible with international brand low-voltage components and intelligent monitoring devices, supporting communication functions for intelligent power distribution systems.
