-5°C~+40°C; the average value within 24h shall not exceed +35°C.For the circuit breaker with thermo-magnetic release,+40°C is set to be the standard temperature for rating.For temperature not between -5°C~+40°C,please contact us for temperature compensation correction:
Not exceed 2000m(Please contact with us for reduction coefficient if altitude at the mounted site exceed 2000m)
3.3 Air conditions:
At mounting site,relative humidity not exceed 50% at the max temperature of +40°C,higher relative humidity is allowable under lower temperature.For example,RH could be 90% at +20°C,special measures should be taken to occurrence of dews.
