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.
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.
