Abstract
An external racking device for remotely racking in and racking out an electrical circuit breaker from a cabinet. The racking device includes a motor head equipped with an electric motor, the electric motor being provided with a rotating shaft ended with an adaptor, and arranged to be coupled with a racking mechanism of an electrical circuit breaker, so that when driven in rotation, the shaft, depending of rotation, trigger either the racking in or the racking out of the circuit breaker from the cabinet. The external racking device further includes monitoring means intended to enable or to disable the operation of the electric motor depending on the status of a circuit breaker to be racked in or racked out from a cabinet.
