摘要:
A circuit breaker module includes an electrically controlled actuator, such as a DC motor, operable to move a breaker contact between open and closed positions. An actuator power supply circuit coupled to an AC power source is configured to selectively energize the actuator, responsive to an actuation input. A processing circuit is configured to control the actuator power supply circuit to activate the actuator in response to breaker command signals, using the actuation input. The processing circuit is further configured to delay activations of the actuator as needed to enforce a predetermined cooling interval between successive actuations.
