MNS Low Voltage Switchgear

The MNS low-voltage switchgear is a modular and assembly-type low-voltage power distribution equipment. It is suitable for power systems with an AC frequency of 50Hz (or 60Hz) and a rated working voltage of 400V to 660V. Its main functions include power distribution, motor control, and reactive power compensation. It is widely used in power plants, substations, industrial and mining enterprises, high-rise buildings, and municipal construction.

Features & Advantages

Modular structure design, easily achieving the integration of ACB with drawer cabinets.
Mixed installation of fixed partition cabinets to improve the cabinet’s installation density
Cabinet design is compact, with the minimum width of the 1600A XP cabinet being only 400mm, and the 3200A XP cabinet requiring only 600mm in width.
With three sets of busbar systems, it can adapt to various complex distribution system requirements.
Drawer interchangeability design allows for easy switching of faulty drawers, minimizing the impact on system operation to the greatest extent.
A single-sided drawer cabinet can accommodate a maximum of 36 distribution circuits.
