Service Environment of MNS Series Low Voltage Switchgear:
a) Air temperature: Maximum temperature: +40℃; Minimum temperature:-5℃; +35℃ average over 24 hours.
b) Humidity: Monthly average humidity 50% in clear air with the maximum +40℃; Higher relative humidity is permitted in lower temperature. For example, the relative humidity is 90% for the temperature of +20℃. Variety of temperature should be taken into consideration of moisture.
c) Altitude above sea level: Maximum installation altitude: 2000m or more higher;

Note: Adaption to other ambient temperatures is possible under consideration of the reduction factors. It must be ensured that indoor conditions are maintained for the place of installation. Moisture condensation on the switchgear components must be prevented by suitable measures such as heating and/or ventilation. Installation up to 1000 m above sea level for higher locations the reduction factors has to be taken into consideration.

Extreme Conditions of MNS Series Low Voltage Switchgear:
A suitable surface treatment is applied to ensure tropicalization. With the aid of accessories and strengthened parts the RMNS system meets the safety requirements for earthquake-prone areas.
· in tropical areas
· in earthquake-prone areas
· in shelters
· in shipbuilding
· in offshore switchboards

Note:

1. The current of vertical busbar is extremely up to2000A@+35℃,(+40℃with cooler) .
2. Protection Degree of IP54 is taken into consideration for special design if needed.
