ABSTRACT:
A waveform recorder device for mounting to an electronic circuit breaker having an electronic trip unit and a communication port is disclosed. The device includes a connector configured to connect with the communication port, and a processing circuit in signal communication with the connector. The processing circuit is responsive to instructions which, when executed by the processing circuit, facilitate responding to a conditional signal received from the circuit breaker, and in response thereto recording waveform information arising from an additional signal received from the circuit breaker.
