Description












MNS Type Low-Voltage Switchgear:
The MNS type low-voltage switchgear (hereinafter referred to as switchgear) is a fully assembled low-voltage switchgear. It features a flexible, modular, multifunctional, reliable, and safe performance. It is suitable for use in metallurgical, petroleum, chemical, mining, and infrastructure industries, serving as a three-phase AC power supply system with a frequency of 50(60)Hz, a rated operating voltage of 380V(400V) or (600V), and a rated current of less than 5000A, for power distribution, centralized motor control, and other low-voltage systems. The switchgear conforms to the following standards: GB7251.1 “Low-voltage switchgear and controlgear”, JB/T9661 “Low-voltage withdrawable switchgear”, and IEC439 “Low-voltage switchgear and controlgear assemblies”.
