摘要： A circuit breaker includes first and second terminals, separable contacts, conductors electrically connecting the contacts between the terminals, and an operating mechanism to open and close the contacts. A current sensor senses current flowing through the contacts and outputs a current value. A number of temperature sensors output a number of temperature values corresponding to a number of the conductors. An electronic trip circuit cooperates with the operating mechanism to trip open the contacts, and includes a processor having a first input inputting the current value, a first routine inputting the current value from the first input and causing the operating mechanism to trip open the contacts responsive to over-current, a number of second inputs inputting the number of temperature values, and a second routine comparing the number of temperature values to a number of limits and causing the operating mechanism to trip open the contacts responsive to over-temperature.

摘要： A debris barrier is for an electrical switching apparatus. The electrical switching apparatus includes separable contacts and an arc chute. The separable contacts generate debris when tripping open in response to an electrical fault. The arc chute has a plurality of splitter plates each having an edge portion and a distal portion located opposite and distal the edge portion. The debris barrier includes a first leg, a second leg, and a middle portion connecting the first leg and the second leg. The middle portion is coupled to one of the separable contacts. At least one of the first leg and the second leg has a first barrier portion and a second barrier portion extending therefrom. The first barrier portion is located proximate the distal portion. The second barrier portion extends from the first barrier portion toward the edge portion in order to redirect the debris toward the edge portion.

The trip circuit is further configured to vary the current threshold during an interval following a closure of the set of the contacts and to provide a fixed current threshold thereafter.
