A rail-mountable electrical device having a “plug-in” receptacle for receiving a pluggable power cord in series with the circuit breaker while mounted on a hot bus bar within a breaker panel. In a first embodiment, the AC circuit breaker/receptacle combination device provides an accessible power outlet direct inside the breaker panel, for example during early construction when wiring of peripheral outlets has not been completed. Disclosed in a second embodiment is a dummy breaker body which comprises a plug receptacle and no circuit breaker. The dummy breaker body seats on the hot bus bar in a breaker panel but does not draw electricity directly, and instead is wired in series with a true circuit breaker proximate on the hot bus bar in a cis- or trans-position. The two body parts, dummy breaker body and circuit breaker, function independently but in series electrical connection. In the various embodiments, NEMA-type or aviation-type plug receptacles are conveniently made accessible within the breaker panel using these devices.

A multipolar electrical protection system including a plurality of devices for switching an electric current. Each switching device has a plurality of compartments each comprising an extinguishing chamber and a pair of separable electrical contacts that are connected to upstream and downstream connection terminals, the separable electrical contacts being movable between open and closed positions under the action of a tripping device. The switching devices are separate from one another, while the upstream terminals of each device are connected by a first connector in order to keep them at one and the same electrical potential and the downstream terminals of each device are connected by a second connector in order to keep them at one and the same electrical potential. The switching devices are controlled by one and the same common tripping device.

A toggle lever connection for connecting at least two toggle levers is disclosed. The toggle levers each include two grooves arranged opposite each other. The toggle lever connection includes a frame and a slider with one hook per toggle lever. The frame and the slider run into each other and can be displaced in relation to each other between a first, open position, in which the toggle lever connection can be placed onto the at least two toggle levers or removed therefrom, and a second, closed position, in which the hooks grip into the grooves of the at least two toggle levers, thereby locking the toggle lever connection to the toggle levers.

A power distribution system includes a bus plug having an electrical switch configured to selectively control energization of the bus plug. The bus plug includes an electrical switch having a control knob operable to selectively control energization of the bus plug, and an actuator having an actuator adaptor coupling that couples movement of the actuator to the control knob. The bus plug includes a partition wall separating the internal volume into a line side and a load side. The bus plug includes an external handle coupled to mechanical linkages, and an adaptor bracket fixed to at least one of the mechanical linkages and oriented to interact with the control knob. The bus plug includes an actuator operable to move the mechanical linkages. Methods of controlling energization of a bus plug with a remote application and communication module configured to operate an actuator are also provided.

An electrical panel assembly comprising at least one circuit breaker and a mounted low-profile circuit breaker lock-out assembly is disclosed. The circuit breaker lock-out assembly includes a first and second mount. The first mount is for mounting to a first end of a circuit breaker housing wall adjacent a circuit breaker switch lever and includes an outward projection having a through-hole. The second mount is for mounting to a second end of the circuit breaker housing wall and includes a pivotally attached arm that is rotatable between an unlocked and locked position in which the arm is aligned with the outward projection allowing a lock to be inserted through the projection through-hole and a corresponding hole in the arm. The arm is shaped to receive the circuit breaker switch lever and hold the lever immobile when the arm is in the locked position and the lock is inserted.

The present invention relates to a state-indicating device (100) for circuit breaker with test function disclose. The state-indicating device (100) includes signal transmission to plurality of indicating devices (100) from the circuit breaker by means of linking features between the circuit breaker and indicating device and also linkage between one indicating device and other indicating device. Indicating device includes a mechanical linkage comprising an actuator connected to hook member (7) and tripping bar (8) with stainless-steel rod (9) being configured to: operate mechanical plate (6) and lever (10), test function actuator (4); to push the microswitch button (19) of a microswitch assembly (12) by selectively On/Off (OF), Signal Default (SD) and SD+OF causing the circuit to change status from Normally Open (NO) to Normally Close (NC); and to show the trip status of the circuit breaker which is mounted to, say the right side of the invented state-indicating device (100).
