Type C. Type C has a magnetic trip activated at 5-10 times the rated current of the circuit breaker. The reference temperature for the thermal tripping characteristics is 30 °C. The Type C characteristic will suit most applications. In rare occurrences when the Type C characteristic does not fully meet the application, Type D magnetic trip
