Abstract
A pair of heaters (16,18) are mounted within a breaker housing (2) in spaced relation to a temperature responsive actuator element (30) for indirectly heating that element in response to current flow in the heaters. Each heater is provided with a wiring terminal member (6,8) for selectively individually connecting one or the other heater in circuit with a branch circuit to be protected. One heater (16) is selected to generate greater amounts of heat than the other heater (18) when subjected to the same current levels. The heaters are individually selectively connected in the branch circuit to be protected whereby the heater (16) producing greater amounts of heat may be utilized in a lower ampere rate application and the heater (18) producing lesser amounts of heat may be utilized in a higher ampere rated application, thereby to selectively permit predetermined current flows in the branch circuit for heating the actuator element (30) to its predetermined temperture to effect separation of the circuit breakers contacts (26).
