The MNS-type low-voltage drawer-type switchgear cabinet (hereinafter referred to as the "switchgear cabinet") is developed by our company through comprehensive improvements based on the reference to the MNS series low-voltage switchgear cabinets of ABB (Switzerland). It is currently a relatively sophisticated low-voltage drawer-type switchgear equipment in China. This product is composed of standardized and serialized modules, and the drawers are equipped with reliable mechanical interlocking devices, which ensure safer and more reliable operation for users.
This switchgear cabinet is suitable for the three-phase five-wire power supply system with an AC frequency of 50 (60) Hz, a rated operating voltage of 400V or 660V, and a rated current of 5000A or below. It can be used in power plants, substations, industrial and mining enterprises, high-rise hotels, airports, docks, and communication centers such as radio and television stations. It serves to control power generation, power transmission and distribution, power conversion, and power-consuming equipment, and performs reactive power compensation on its main busbar through a capacitor compensation cabinet. It complies with the standards: GB7251.1 <Low-Voltage Switchgear Assemblies> and IEC60439 <Low-Voltage Switchgear and Controlgear Assemblies>.

The ambient air temperature shall not be higher than +40°C or lower than -5°C, ,and the average temperature within 24 hours shall not exceed +35°C.
The relative humidity of the ambient air shall not exceed 50% when the maximum temperature is +40°C, and it can be higher at lower temperatures (e.g., 90% at +20°C). However, it should be taken into account that moderate condensation may occasionally occur due to temperature changes.
For indoor use, the altitude of the installation site shall not exceed 2000m.
It should be installed in a place free from severe vibration and impact, and where electrical components will not be corroded.
