The present invention employs a separate rotation-adjusting member, which allows a position of a circuit breaker or a transformer to be recognized from outside without an error.

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.

A lead screw operated drawout mechanism for an electrical system is disclosed. The lead screw operated drawout mechanism includes a lead screw, a nut, a drive shaft and a connecting mechanism. The lead screw is supported on a support frame in a way such that the lead screw rotates with respect to the support frame. The nut is disposed on the lead screw, wherein rotary motion of the lead screw facilitates linear motion of the nut on the lead screw. The drive shaft is rigidly disposed on the nut and configures linear motion along with the nut. The connecting mechanism is functionally connected to the drive shaft and the electrical system for facilitating activation and de-activation of the electrical system.

A secondary disconnect assembly for a switching device includes a first mounting bracket configured to support a secondary connector of a switching device system, a telescopic arrangement connected to the first mounting bracket, a slider connected to the telescopic arrangement, and a second mounting bracket including a projection. The second mounting bracket is operable to move with the switching device. The slider is engageable with the projection and movable with the second mounting bracket in an automatic operation of the secondary disconnect assembly. The slider is disengageable from the projection and movable with respect to the second mounting bracket in a manual operation of the secondary disconnect assembly.

An automatic autonomous redundant switch configured for providing energy from either a first power source or a second power source to a load is provided. The automatic switch includes a first automatic transfer switch (ATS) and a second ATS. The automatic switch further includes an interconnecting bus configured to connect the first ATS and the second ATS, and at least one controller configured to control the operation of the first ATS and the second ATS. Still further, the first ATS and the second ATS each include a respective transfer-switch mechanism, a respective bus attachment configured to connect to the interconnecting bus, and a respective motorized rack-out mechanism having a powered actuator.

The present disclosure relates to a circuit breaker positioning system and method including a circuit breaker casing and circuit breaker cell for connecting and disconnecting a circuit breaker to an external electrical circuit. The circuit breaker positioning system includes a motion system for receiving a rotational force from an external source and translating the rotational force into a displacement of the casing relative to the cell.
