Introduction

MNS type low-voltage withdrawable switchgear (hereinafter referred to as "switching device") is a new type of low-voltage switchgear designed and developed by our company in combination with the development trend of my country's low-voltage switchgear, and improving the selection of electrical components and the structure of the cabinet. equipment

Switchgear is suitable for power systems with AC 50Hz (GOHz) and rated operating voltage 66OV and below, as power generation, transmission, distribution, power conversion, etc. and the control of power consumption equipment.

In addition to general land use, switchgear can also be used in offshore oil drilling platforms and nuclear power plants after special treatment.

The switchgear complies with the standards of GB7251 "Low-voltage switchgear and control equipment", JB/T9661 "Low-voltage withdrawable switchgear" and IEC60439-1 "Low-voltage switchgear and control equipment".
