1. Ambient air temperature: -5℃+40℃and the average temperature should not exceed +35℃ in 24h.
2. Air condition: With clean air. Relative humidity should not exceed 50% at +40℃. Higher relative humidity i
s allowed at lower temperature. Ex. 90% at +20℃. But in view of the temperature change, it is possible that
moderate dews will produce casually.
3. Altitude above sea level should not exceed 2000M.
4. The device is suitable to the transportation and store with following temperature:-25℃ ~+55℃, in short
time (within 24h) it reaches +70℃. Under the limiting temperature, device should not suffer damage that
can[1]t recover, and it can works normally under normal conditions.
5. If the above operating conditions not meet user’s demand. Consult with manufactory.
6. Technical agreement should be signed additionally if the device is used for marine petrol drill taken
platform and nuclear power station
MNS LV withdrawable switchgear (hereinafter referred to as device) is manufactured by standard
module through consulting MNS series low voltage switch cabinet of Switzerland ABB Company,
and synthetically improved. The device is applicable to the system with AC 50Hz, rated working
voltage 660V and below, used as control device for various power generation, transmission, distribution
, power transfer and power consumption device. It is widely used in low voltage distribution system of
various mining enterprise, tall building and hotel, municipal construction etc. Besides the general land
use, after special disposal, it also can be used for marine petrol drill taken platform and nuclear power
station. The device accords with international standard IEC439-1 and national standard GB7251.1.
