Abstract

A circuit breaker includes two or more poles electrically connected between a power supply and a contactor. Each of the two or more poles comprises a switch. The circuit breaker includes one or more voltage measuring devices configured to measure at least one phase-to-phase voltage level, and one or more current detecting devices configured to detect current going through each of the two or more poles. The circuit breaker further includes a control circuitry configured to: monitor the at least one phase-to-phase voltage level; in response to determining the at least one phase-to-phase voltage level is within a threshold range, close corresponding switches; in response to detecting current flowing through at least one of the two or more poles, maintain the corresponding switches in a closed position; and close all additional switches associated with the two or more poles after a period of time.
