Overview
The MNS type low-voltage withdrawable switchgear is a new generation of low-voltage switchgear developed according to market demand. The product technical standards comply with IEC439 "Low-voltage switchgear and controlgear" and GB7251 "Low-voltage switchgear" standards.
MNS type low-voltage withdrawable switchgear is suitable for power plants, substations, petrochemical, metallurgical rolling, light industry and textile factories and mines, residential areas, high-rise buildings and other places, as AC 50-60Hz, rated operating voltage AC 660V and below power system distribution equipment for power conversion, distribution and control.
Environmental Conditions of Use
1) Ambient air temperature not higher than +40℃, not lower than -5℃, and the average temperature within 24h not higher than +35℃.
2) Atmospheric conditions: Clean air, relative humidity not exceeding 50% at the highest temperature of +40℃, higher relative humidity is allowed at lower temperatures, e.g., 90% at +20℃, but the temperature change should be considered, condensation may occur occasionally.
3) Altitude not exceeding 2000m
4) This device is suitable for the following temperature range during transportation and storage: -25℃ to +55℃, up to +70℃ for a short period (not exceeding 24h). Under these extreme temperatures, the device should not suffer any irreversible damage and should be able to operate normally under normal conditions.
5) If the above applicable conditions cannot be met, it should be resolved through consultation between the user and the manufacturer.
6) When this device is used in offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.
