A linear actuator assembly is for an electrical switching apparatus, such as a multi-pole circuit breaker. The circuit breaker includes a plurality of pole units each having separable contacts. The linear actuator assembly includes a base unit comprising a housing, and a plurality of linear actuators. Each linear actuator is mounted within the housing in alignment with a corresponding one of the pole units. Each linear actuator actuates the separable contacts of the corresponding one of the pole units. A controller is adapted to control actuation of the linear actuators. |
