The MNS type low-voltage withdrawable switchgear (hereinafter referred to as the switchgear) is composed of a series of standardized and integrated modules. The drawer has a reliable mechanical interlocking device to make users more reliable. is using.

The switchgear is suitable for AC 50 (60) Hz, rated voltage 400V, 660V, 5000A rated current and the following three-phase five-wire power supply system, used in power plants, substations, industrial and mining enterprises, construction hotels, airports, terminals and radio and television Like the communication center, as the main bus for power generation, transmission and distribution, power conversion and energy consumption control equipment and capacitor compensation cabinets, reactive power compensation is the main line.

Comply with national standards: IEC60439 "Low-voltage switchgear and control equipment" GB7251.1 "Low-voltage switchgear and control equipment"

The ambient air temperature is not higher than +40℃, not lower than -5℃, and the average temperature of 24h is not higher than +35℃.

The relative humidity of the environment at 9:28 temperature does not exceed 50%, and it has a higher relative humidity at low temperatures, such as 90% at 20°C, but considering that temperature changes may cause moderate gel accidents.

The altitude of the location when used indoors does not exceed 2000m.

It should be installed without severe vibration and impact, and do not use electrical components in corroded parts.
