Please see below figures below showing the maximum Terminal Temperature for the Easypact CVS MCCBs as per IEC 60947-2
Easypact CVS100 (fixed) : 100 ℃
Easypact CVS 160/250 (fixed): 110 ℃
Easypact CVS 400/630 (fixed): 110 ℃
However, it is recommend that the calculation is based on 70 Degree C cable as it is possible that heat from the cable may flow into the circuit breaker and effect the thermal characteristic. The multi core cable is normally glanded elsewhere and terminated at the circuit breaker as individual cores, which improves cooling.
NOTE: 90 degree cables are not permitted on these MCCB's
