Depending on the technology used temperature does affect the tripping point of a circuit breaker. What does this mean in real terms? If you are the type of designer that runs components to the max then it is very important to consider this derating factor. ===>>>OOPS…You are not logged in for this group!

A circuit breaker will be damaged by a higher than designed fault current that it has to make/break…this is the “Rated Breaking Current”, normally referred to as the kA of the circuit breaker. If this energy was of the sort to melt the contacts together before the circuit breaker had time to react we have […]
