摘要： An apparatus for providing electrical protection to a protected circuit in electrical communication with an electrical source is disclosed. The apparatus includes a housing, a separable conduction path in series connection with the protected circuit, an operating mechanism in operable communication with the separable conduction path, a thermal element in thermal communication with the separable conduction path, and an electronic trip unit in signal communication with the thermal element and in operable communication with the operating mechanism. The electronic trip unit is adapted to sense a voltage drop across the thermal element and to trip the operating mechanism in response to the sensed voltage drop being in excess of a first trip threshold.

摘要： A method for recording and having analyzed waveform data associated with an electronic circuit breaker having an electronic trip unit is disclosed. The electronic trip unit has a communication port and is capable of providing to the communication port a first signal representative of a phase current passing through the circuit breaker, and a second signal representative of a conditional event at the circuit breaker. The method includes facilitating the connection of a waveform recorder device to the communication port of the electronic trip unit; facilitating recording in a first memory of the waveform recorder device in a circular queue fashion information relating to the first signal received from the electronic trip unit; and, in response to the second signal received from the electronic trip unit, facilitating the stopping of the recording in the first memory.

摘要： An electronic trip unit for a circuit breaker is disclosed. The electronic trip unit has a processing circuit, a real time clock chip, and a power source for powering the real time clock chip in the absence of current in the circuit breaker. The processing circuit is responsive to input signals representative of a current in the circuit breaker, and productive of a trip signal for tripping the circuit breaker. The real time clock chip is in signal communication with the processing circuit. In response to an off event at the circuit breaker following a current flow condition thereat, the real time clock chip is configured to generate time information for use by the processing circuit, which is configured to apply the time information to calculate a cooling effect arising from the circuit breaker being off, thereby providing for thermal memory.
