摘要: An electronic trip unit for a circuit breaker is disclosed. The electronic trip unit has a processing circuit, and a real time clock circuit that is operational 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 the real time clock circuit 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 circuit is configured to generate time information relating to the circuit breaker being off as a result of the off event for use by the processing circuit.

摘要: A control system includes an enclosure, a control panel, and a plurality of controls, indicators, or both mounted on the control panel or in the enclosure. At least some of the plurality of controls, indicators, or both are configured to wirelessly communicate with each other inside the enclosure, and at least some controls including wirelessly controlled relays are configured to control devices outside the enclosure. Also, the wirelessly configured controls, indicators, or both are further configured to communicate with a plurality of other controls, indicators, or both in the control system.
