Hi everbody,
According to IEC 60947, the circuit breaker is tested using "Temperature rise test" which is done at normal operational current. This standard defines the accepted temperature rise for this test. My question: Is there any standard or code that defines the temperature rise limits for the circuit breaker in the case of overload? By overload I mean that the current is greater than In (Nominal current)
