Low-voltage switchgear MNS

ACindustrialpower plant

MNS(HY) low voltage complete switchgear is a new generation of low voltage switchgear introduced and developed by Huayi Electrical Group according to the market demands. The product meets requirements of IEC439 Low Voltage Switchgear and Controlgear Assemblies and GB7251 Low Voltage Complete Switchgear. MNS(HY) low voltage drawer type switchgear is suitable to be used for AC 50-60HZ power distribution system of 660V of rated working voltage for power station, transformer substation, petrochemical industry, metallurgy rolling, etc. industrial and mining enterprises and high rise building for conversion of power and control and consumption of equipment. Using environment: 1. - Surrounding air temperature: >-5°C and <+40°C, average temperature in 4 hours: <+35°C. 2. - In clean air, the relative humidity should <50% at +40°C of highest temperature; high relative humidity might be allowed at low temperature, for example, 90% at + 20°C; condensation might appear some times for change of temperature. 3. - Altitude: no higher than 2,000m. 4. - The device is suitable to be transported and stored at the following temperatures: between -25°C and 55°C, up to +70 °C in a short time (not more than 24h). The device should be free from unrecoverable damage at the extreme temperature and should work properly in normal conditions. 5. - The user should negotiate with the manufacturer when the above conditions cannot be met. 6. - Another technical agreement should be signed with the device is used for offshore petroleum platform and nuclear power plant.
