Abstract
A circuit breaker includes a breaker enclosure, a plurality of conductor connections, and a temperature sensor. The breaker enclosure contains internal components that include a trip unit. The plurality of conductor connections electrically couple the trip unit to a plurality of power conductors. The temperature sensor is located to sense heat radiated by the conductor connections and is positioned inside the enclosure.
