Abstract
A circuit breaker may include a first magnetic actuator connected to a first single-phase vacuum interrupter, a second magnetic actuator connected to a second single-phase vacuum interrupter, and a third magnetic actuator connected to the third single-phase vacuum interrupter. Each magnetic actuator is configured to receive an interrupt signal, and in response, actuate a respective vacuum interrupter connected thereto into an open circuit condition. Each magnetic actuator includes a fixed core, a plurality of permanent magnets surrounding the fixed core, and a movable core received within the fixed core. A controller generates an interrupt signal to a respective magnetic actuator and interrupts one or more of the first, second and third single-phase vacuum interrupters.
