Low Voltage Switch Cabinet

Product Overview

The MNS withdrawable low-voltage switchgear is a modular withdrawable complete power distribution equipment. It is widely applied in low-voltage power distribution for industrial plants, commercial buildings, photovoltaic & energy storage projects, sewage treatment plants, adopting independent drawer unit solutions to realize centralized power supply and protection for multiple load circuits.

Core Product Advantages

• Safe Modular Withdrawable Design

Each circuit corresponds to an independent drawer unit with three-position mechanical interlock (Working / Test / Isolation). The drawer cannot be pulled out under closing status to avoid risks of live plugging. Maintenance of a single faulty circuit can be carried out without powering off the whole cabinet, greatly shortening downtime.

• Convenient Operation & Quick Replacement

Faulty drawers can be directly extracted and replaced by spare drawers for efficient on-site maintenance. Drawers adopt standardized universal dimensions to support flexible capacity expansion.

• Neat Layout & Visualized Maintenance

Cabinet doors are equipped with operating handles, multi-function meters and running indicator lights. Operating data such as current and voltage can be checked without opening the cabinet.

• High Compatibility for Complete Sets

The cabinet can be fitted with MCCB, AC contactors, thermal overload relays, smart meters, surge protection devices and other components. Customization is available for motor circuits, lighting circuits, frequency conversion circuits, etc.

• Reliable Protection Performance

The cabinet is made of cold-rolled steel plate with IP30 protection grade. Primary power circuits and secondary control circuits are isolated to prevent fault propagation.

Application Scenarios

Power distribution in factory workshops, HVAC water pump electric control, sewage treatment plants, commercial complex power rooms, auxiliary power systems of photovoltaic and energy storage stations, low-voltage power distribution for data centers.
