Abstract
A circuit breaker apparatus is provided and includes a trip mechanism which is coupled to an electrical circuit and which is configured to interrupt an operation of the electrical circuit when the trip mechanism is actuated, an electronic trip unit in signal communication with and configured to actuate the trip mechanism when pre-selected conditions are satisfied, and a rating plug coupled to the electronic trip unit and configured to operate in a first mode in response to a receipt of a transmitted control signal at the rating plug, and to otherwise operate in a second mode, the first and second modes being respectively associated with first and second ones of the pre-selected conditions to be correspondingly transmitted to the electronic trip unit by which the electronic trip unit determines whether to actuate the trip mechanism.
