Abstract

A vacuum circuit breaker (VCB) assembly includes a single motor configured to rotate at least one rotor, a VCB having a breaking mechanism configured to control current flow through the VCB and a first electromagnetic clutch configured to selectively engage the at least one rotor with the breaking mechanism to charge the breaking mechanism. The VCB assembly also includes an undercarriage configured to support the VCB assembly and to move the VCB assembly from a first position to a second position and a second electromagnetic clutch configured to selectively engage the at least one rotor with the undercarriage to drive the undercarriage.
