MNS type Low voltage withdrawable switchgear

Product introduction

This series of low-voltage withdrawable switchgear is a modular cabinet type assembled by factory with standard  modules.

This series of low-voltage withdrawable switchgear is suitable for power plants,substations,petrochemicals,   metallurgical roling steel,transportation energy,light industrial textiles and other factories and mines,residential    quarters,high-rise buildings and other places,as power conversion,distribution and control of the power distribution    equipment of power system with AC 50~60HZ,rated working voltage AC 660V and lower.

This device complies with GB7251.1 "Low-voltage switchgear and controlgear assemblies-Part 1:General   Provisions"and GB/T7251.1 "Low-voltage switchgear and controlgear assemblies-Part 2:Power switchgear and   controlgear assemblies°national professional standards.

Conditions of use

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

Atmosphericconditions:air is clean,relative humidity is not more than 50%at a maximum temperature of+40°    C,and a higher relative humidity is allowed at a lower temperature,for example,90%at+20°C,butit should be con-   sidered that temperature changes is possible to accidentally produce condensation.

Altitude does not exceed 2000m

This device is suitable for transport and storage at temperatures ranging from-25°C to+55°C,up to+70°    Cin a short period of time(not exceeding 24h),under these limiting temperature the device should not be subjected to any unrecoverable damage and should work properly under normal conditions.

If the above conditions of use cannot be met,it should be resolved by the user and the manufacturer.

When the device is used in offshore oildiling platforms and nuclear power plants,a separate technical agreement should be signed.
