Description
MNS Low Voltage Draw-out Switchgear
The MNS series is a highly versatile modular low-voltage draw-out switchgear, designed for AC low-voltage distribution systems. It supports flexible configuration of multiple functional units including incoming line, bus tie, feeder, capacitor compensation and motor control, to meet diversified power distribution and control demands in various scenarios.
Core Structural Features
Fully modular assembled structure
All basic structural components of the cabinet are galvanized, connected and fastened by self-tapping locking screws, with high structural strength, flexible on-site assembly and convenient scheme expansion.
25mm standardized modular design
Internal components and compartment sizes all comply with the 25mm modulus standard. Functional units can be freely combined according to project requirements, with strong scheme adaptability to customized demands.
High interchangeability of draw-out units
Draw-out functional units of the same specification can be directly interchanged, which greatly improves operation and maintenance efficiency and shortens power outage time in case of faults.
Diversified cabinet specifications
Cabinet width covers multiple specifications from 400mm to 1000mm, adapting to different current levels and on-site installation conditions.
