The MNS low-voltage withdrawable switchgear (referred to as the switchgear) is composed of two parts: the power center cabinet (PC) and the motor control center cabinet (MCC). It is applicable to the control and distribution system with an AC frequency of 50-60HZ and a rated working voltage of 660V or less. It is used by power users such as power plants, substations, industrial and mining enterprises, etc., for the conversion, distribution and control of electric energy in power distribution, motor control and lighting and other distribution equipment.

In addition to general land use, this switchgear can also be specially treated and used in offshore oil drilling and production platforms and nuclear power plants. This switchgear complies with IEC439, VCE0660 Part 500 and the national standard GB7251-05 "Low-voltage Switchgear Assemblies", as well as the industry standard JB/T9661-1999 "Low-Voltage Withdrawable Switchgear Assemblies".

Atmospheric conditions: The air is clean, and the relative humidity does not exceed 50% at the maximum temperature of +40℃. Higher relative humidity is allowed at lower temperatures, for example, 90% at +20℃. It should be taken into account that due to temperature changes, condensation of humidity may occur occasionally.

The altitude does not exceed 2000 meters.

This device is suitable for transportation and storage processes within the following temperature range: -25℃ to +55℃, and can reach +70℃ for a short period of time (not exceeding 24 hours). Under these extreme temperatures, the device should not suffer any irreversible damage and should be able to operate normally under normal conditions. If the above usage conditions cannot be met, the user and the manufacturer shall negotiate and resolve the issue.
