A remote-controlled mechanism according to an embodiment is used for coupling to a protective switching device to use a controllable drive device of the remote-controlled mechanism to actuate the coupled protective switching device. To this end, the remote-controlled mechanism includes: an actuating element operatively connectable to an actuating element of the coupled protective switching device and actuatable either by a remotely controllable drive device of the remote-controlled mechanism or manually; one or more sensor devices for capturing position data relating to a position of the actuating element of the remote-controlled mechanism; and a controller for evaluating the captured position data and for controlling the drive device via control commands. The controller is designed to disable the drive device upon an evaluation of the position data and/or of the control commands revealing that the actuating element of the remote-controlled mechanism has been switched off manually.

An electric operating device for a circuit breaker that includes a housing, a transmission mechanism is installed in the housing, and a side wall of the housing serves as an operation surface and is provided with a first sliding groove communicated with the interior of the housing; a sliding rod is installed in the housing; a driving member controlled by the transmission mechanism is installed on the sliding rod; the driving member is provided with a closing operation portion and an opening operation portion; the driving member passes through the first sliding groove and extends out of the housing; the driving member moves along the sliding rod under the control of the transmission mechanism; and the closing operation portion and the opening operation portion operate a handle of the circuit breaker to be closed and opened respectively.

A modified trip lever for a remote controlled miniature circuit breaker comprises a trip lever and a separate kicker lever, which perform alternate functions to either automatically open the main contacts in response to a trip event or alternately open or close the contacts under remote control. The kicker lever rotates clockwise on a pivot in response to an actuator receiving a remote control open signal, to open the contacts by forcing a transverse tab on the kicker lever against a blade carrying a moveable main contact aligned with a stationary main contact. The kicker lever rotates counterclockwise to close the contacts in response to the actuator receiving a remote control close signal. The trip lever mounted on the same pivot, is configured to automatically open the contacts in response to a trip event, by pushing against the back side of the tab of the kicker lever.

A remote load switching circuit breaker includes a primary contact; a secondary contact in series with the primary contact and coupled to a secondary contact driving circuit, where the secondary contact is switched on and off remotely by a user using a user device communicatively coupled to the remote load switching circuit breaker via wireless communications technologies; a shunt element structured to measure a shunt voltage drop and to tap power from a line side of the primary contact; a control circuit comprising a controller and a communication module, the controller including a firmware; and a power supply and sensing circuit structured to supply power to the control circuit and to sense various voltages, where the secondary contact is fully powered by the power supply and sensing circuit.

A circuit interrupter includes a frame, a set of separable contacts that can be generally stated as including a stationary contact and a movable contact, the stationary contact being affixed to the frame, a shaft movably situated on the frame, the movable contact being situated on the shaft, a drive system situated on the frame and operable to move the shaft with respect to the frame between a first position and a second position, the set of separable contact being a CLOSED state in the first position of the shaft and being in an OPEN state in the second position of the shaft, and a brake that can be generally stated as including a mass movably situated on the frame, the shaft being structured to engage the mass and to cause the mass to be in motion when moving from the first position toward the second position.

The present invention relates to an automatic control device for a padlock which enables automatic control of the padlock connected to a circuit breaker installed in a distribution board of semiconductor or LCD equipment. In the present invention, a pair of cylinders, which can supply and cut off electric power to and from a load terminal, is directly installed on top of the circuit breaker installed in the distribution board, so that a switch of the circuit breaker is turned on/off as the pair of cylinders selectively operates according to an external control signal. As a result, it is unnecessary to separately install the padlock for switching on/off the circuit breaker.

The present invention refers to a low voltage circuit breaker with a control device for re-closing said low voltage circuit breaker. The control device is provided with an actuating element, comprising a shape memory material and operatively associated with maneuvering means for the circuit breaker. When this shape memory material performs a state transition, the actuating element causes the movement of said maneuvering means from a first operative position, associated with an open configuration of the circuit breaker, to a second operative position, associated with a closed configuration of the circuit breaker.

A circuit breaker includes a housing having a channel formed therein, the channel being defined by at least one side wall having a detent formed therein, a circuit breaker mechanism, a switch handle configured to toggle the circuit breaker, and an actuator module adapted to move the switch handle from the off position to the on position. The module includes a flexible portion having a protrusion formed thereon, the protrusion being sized, shaped and located to engage the detent when the module is mounted within the channel. The module also includes a locking clip moveable from an unlocked position, in which flexing of the at least one flexible portion is permitted, and a locked position, in which flexing of the at least one flexible portion is limited or prevented, such that when the module is mounted within the channel, removal of the module is inhibited.

A remote load switching circuit breaker includes a primary contact; a secondary contact in series with the primary contact and coupled to a secondary contact driving circuit, where the secondary contact is switched on and off remotely by a user using a user device communicatively coupled to the remote load switching circuit breaker via wireless communications technologies; a shunt element structured to measure a shunt voltage drop and to tap power from a line side of the primary contact; a control circuit comprising a controller and a communication module, the controller including a firmware; and a power supply and sensing circuit structured to supply power to the control circuit and to sense various voltages, where the secondary contact is fully powered by the power supply and sensing circuit.
