Patent ID: 11495956

Abstract:
A trip apparatus has a power terminal, an actuator, a rectifier coupled to the power terminal, a selector, and a processor, the actuator having a pusher member and a coil, the pusher member movable between a first position that does not actuate an actuator interface of a connected circuit breaker and a second position that actuates the actuator interface. The processor has a first input, a second input, and an output, the first input of the processor is coupled to the output of the rectifier, the second input of the processor coupled to an output of the selector, and the output of the processor coupled to the actuator. The processor determines a threshold based on a select signal received at the second input of the processor, and compares a voltage at the first input of the processor to the threshold. The processor controls the coil to selectively control the pusher member in the first or second position based on the comparison of the voltage at the first input of the processor to the threshold.
