MNS low-voltage withdrawable switchgear
A profile,
MNS low-voltage withdrawable switchgear is suitable for power plants, substation, petrochemical, metallurgical steel equivalent residential district of factories and mines, high-rise buildings and other places, as ac 50 to 60 hz below the rated working voltage of ac 660 v and power distribution system of the transformation and energy consumption equipment control.
Second, the use environment
Ambient air temperature is not higher than 40 ° C +, not less than 5 ° C, and its average temperature is not higher than within 24 h + 35 ° C.
Atmospheric conditions: clean air, relative humidity at the highest temperature is + 40 ° C is less than 50%, at lower temperature when allowed to have a high relative humidity, such as + 20 ° C at 90%, but should be considered due to temperature changes, is likely to be accidentally produces a moderate amount of condensation. The altitude does not exceed 2000 m.
This device adapted to the following: transportation and storage temperature to 25 ° C between the range of 55 ° C, in a short period of time (not more than 24 h) of up to 70 ° C, in these extreme temperature should not be any unrecoverable damage to the device, and under normal conditions will be able to work properly.
If the above conditions of use can't meet, shall be settled by users and manufacturers to negotiate.
