MNS Type Low-Voltage Drawout Switchgear

Overview

The MNS type low-voltage drawout switchgear uses modular design and drawout functional units, meeting GB/T 7251.1 and IEC 61439. With main busbar rated current up to 6300A and short-circuit withstand up to 100kA, it suits industrial and municipal distribution demanding supply continuity, combining power center (PC) and motor control center (MCC) functions.

Features

• Modular structure with standard modules 8E/4, 8E/2, 8E, 16E, 24E for high circuit density per section;
• Drawout functional units can be replaced and maintained without cutting the main busbar, reducing downtime;
• Three-position indication (connected/test/disconnected) with mechanical interlock and misoperation protection;
• Cabinet in aluzinc or powder-coated cold-rolled steel, protection up to IP40/IP54;
• Integrable comprehensive protection, smart monitoring and communication modules for distribution automation.

Selection Advice

Choose fixed-partition or drawout schemes by circuit count, per-circuit capacity and operating frequency. For production lines with strict process continuity, drawout schemes shorten fault recovery time.

Applications

Industrial distribution in petrochemical, metallurgy and automotive; data center and hospital LV distribution; urban rail transit power distribution.
