Product Introduction

MNS type low-voltage withdrawable switchgear (hereinafter referred to as switchgear) is developed by our company after referring to the MNS series low-voltage switchgear of ABB company in Switzerland and comprehensively improved, and it is currently the most complete low-voltage withdrawable switchgear in China. The products are all made up of standardized, series of modules, and the drawers have reliable mechanical interlocks, making them safer and more reliable for users to use.

This switch cabinet is suitable for AC 50 (60) Hz, rated working voltage 400V, 660V, rated current 5000A and below three-phase five-wire power supply system, can be used in power plants, substations, industrial and mining enterprises, buildings, hotels, airports, docks and radio and television and other communication centers, as power generation, transmission and distribution, power conversion and power consumption equipment control, and through the capacitance compensation cabinet for its main bus reactive power compensation. Conform to the standard: GB7251.1 "low-voltage switchgear" IEC60439 "low-voltage switchgear and control equipment"

Model Meaning

Working Conditions

◇ The ambient air temperature is not higher than +40°C, not lower than -5°C, and the average temperature is not higher than +35°C within 24h;

◇ The relative humidity of the surrounding air does not exceed 50% at +40°C, and there is a higher relative humidity at lower temperatures, such as 90% at +20°C, but considering that moderate condensation may occasionally occur due to temperature changes;

◇ For indoor use, the altitude of the place of use shall not exceed 2000m;

◇ It should be installed in a place where there is no violent vibration and impact, and where electrical components are not corroded without use.
