MNS Type AC Low Voltage Withdrawable Switchgear

Product Introduction

• The MNS low voltage withdrawable switchgear is a modular, standardized, and multifunctional low-voltage distribution cabinet assembled in the factory using standard components.
• It is suitable for AC 50–60 Hz systems with a rated working voltage of 380 V (660 V) and a maximum rated current up to 6300 A, in three-phase four-wire and three-phase five-wire power systems.
• The system is widely used in power plants, substations, petrochemical, metallurgical, transportation energy, light industry, textile industries, as well as residential communities and high-rise buildings. It is designed for low-voltage distribution and motor control systems requiring high reliability.

Application Scenarios
