2. Operating conditions
NM8, NM8S
Moulded Case Circuit Breaker
1. General
2.1 Temperature: -5
℃~+40
℃; the average value within
24h shall not exceed +35
℃ ; for the circuit breaker
with thermo-magnetic release, +40
℃ is set to be the
standard temperature for ratings. Special utilization,
please refer to coefficients indicated on page 21 for
temperature compensation correction;
2.2 Altitude:
≤2000m;
2.3 Pollution grade: Grade 3;
2.4 Air conditions:
At mounting site, relative humidity not exceed 50%
at the max temperature of +40
℃ , higher relative
humidity is allowable under lower temperature.
For example, RH could be 90% at +20
℃ , special
measures should be taken to occurrence of dews.
