Operation Conditions. Temperature: ~+0 ; the average value within h shall not exceed +.(please contact with us if temperature at the mounted site beyond above values); for the circuit breaker with thermomagnetic release, +0 is set to be the standard temperature for ratings. For temperature not between ~+0, please contact us for temperature compensation correction;. Altitude: not exceed 00m (Please contact with us for reduction coefficient if altitude at the mounted site beyond 00m). Pollution grade: Grade ;. Air conditions: At mounting site, relative humidity not exceed % at the max temperature of +0, higher relative humidity is allowable under lower temperature. For example, could be % at +, special measures should be taken to occurrence of dews...
