1.1 Thông số chung

1.1 Temperature: -50C~+400C; the average value within 24h shall not exceed +350C.(please

refer to coefficients on P107 for temperature compensation correction); for the circuit breaker

with thermo-magnetic release, +400C is set to be the standard temperature for ratings. For

temperature not between -50C~+400C, please contact us for temperature compensation correction.

1.2 Altitude: not exceed 2000m (Please contact with us for reduction coefficient if altitude

at the mounted site beyond 2000m).

1.3 Pollution grade: Grade 3

1.4 Air conditions

At mounting site, relative humidity not exceed 50% at the max temperature of +400C , higher

relative humidity is allowable under lower temperature. For example, RH could be 90% at

+200C , special measures should be taken to occurrence of dews.
