Circuit interrupter including point-on-wave controller and voltage sensors

摘要

A circuit breaker includes a circuit breaker housing and a plurality of independent poles. Each of the independent poles includes separable contacts, a voltage sensor mounted on or within the circuit breaker housing and being structured to sense voltage operatively associated with the separable contacts, and an electro-magnetic actuator structured to open and close the separable contacts. A point-on-wave controller is housed by the circuit breaker housing and cooperates with the sensors and the actuators of the independent poles to independently and synchronously open and close the separable contacts of the independent poles.
