Abstract
A solid-state circuit breaker configured to turn off electronics before a pair of opposing primary main contacts are opened. The solid-state circuit breaker includes a main mechanism including a pair of opposing primary main contacts. The solid-state circuit breaker further includes electronics including semiconductors and software algorithms that control the power and can interrupt currents. The solid-state circuit breaker further includes a switching system including a secondary switch that is configured to be actuated prior to opening of the primary main contacts. The secondary switch is configured to turn off the power to the electronics of the solid-state circuit breaker before the primary main contacts are opened to eliminate or reduce electrical arcing across the primary main contacts.
