Abstract
A circuit interrupter includes a temperature detection system that is configured to detect a measured temperature of at least one of a line conductor, a load conductor, a movable contact, and a stationary contact during operation of the circuit interrupter. The measured temperature is representative of an extent of wear of the set of separable contacts. In one embodiment the temperature detection system includes a temperature sensor that is an infrared sensor. In another embodiment, the temperature detection system includes a temperature sensor that is in physical contact with an electrically conductive structure within the circuit interrupter and therefore additionally employs a voltage filter that filters a line voltage from the signal from the temperature sensor. In another embodiment, the temperature detection system employs a temperature sensor that is in physical contact with an electrically conductive structure, but a wireless transceiver is used to wirelessly communicate the measured temperature.
