—Miniature Circuit Breaker SU 200 M DeratingDeviating ambient temperature
The rated value of the current of a miniature circuit breaker of SU 200 M series refers to a reference ambient temperature of 30 °C acc. to IEC/EN 60947-2 and 40 °C acc. to UL/CSA. The fol-
lowing tables show derating factors for ambient temperature from -40 °C to 70 °C for the character-istics C, K, Z.

—Miniature Circuit Breaker SU 200 M DeratingInfluence of adjacent devices, internal resistance and power loss
Influence of adjacent devicesIf several miniature circuit breakers are installed di-rectly side by side with high load on all poles, a cor-rection factor has to be applied to the rated current (see table). If distance pieces are used, the factor is not to be considered.
