Embodiments of the disclosure provide for a system and method for determining a circuit breaker position in a power distribution/load center. In one embodiment, the load center includes a plurality of circuit breakers. Each circuit breaker includes a base and a plurality of contact components coupled to the base. In that regard, an activation of a combination of the contact components indicates a position of the circuit breaker within the load center. The activation of the combination indicates that one or more of the contact components is in contact with one or more pegs coupled to the load center. When this occurs, a data transceiver coupled to each of the contact components transmits a data signal. The data signal includes a plurality of data bits, where each data bit indicates whether a corresponding contact component of the combination is activated or not activated.

A breaker includes a stationary contact, a movable contact, an operation device including a link portion liked to the movable contact and including an output lever rotatably supported, the operation device operating rotation of the output lever in accordance with a first control signal for a command for pulling out the movable contact and a second control signal for a command for inserting the movable contact, and an auxiliary contact to switch between turn-on and turn-off of an input of the first control signal and the second control signal to the operation device in conjunction with operation of the output lever, the auxiliary contact being able to be used in a circuit configuration to monitor a state of the operation device. The output lever rotates so as to operate a first link portion on a side toward a first direction with respect to a rotational center of the output lever.

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).

An adapter for installing at least one accessory part into an electrical switch. The accessory part has at least one interface and the electrical switch has a housing and at least one actuation element. The adapter has at least one deflection gear mechanism, which, when the adapter is installed in the housing of the electrical switch, is arranged in an operatively connecting manner between the at least one interface of the accessory part and the at least one actuation element of the electrical switch.

A shunt trip assembly structured to be operatively coupled to a number of circuit breakers uses a lever to actuate an operating mechanism of the circuit breakers and uses a selectively powered solenoid to power the lever. The shunt trip assembly is composed from a standardized shunt assembly designed for use with a plurality of different solenoid coils, such that a given standardized shunt assembly will be operative regardless of which of the solenoid coils are added to the standardized shunt assembly. The shunt trip assembly requires less than 10 amps of current to operate; can be powered by any of a 12 volt AC/DC, 24 volt AC/DC, or 48 volt AC/DC power source; and is functional in temperatures ranging from −40° C. to +60° C.

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.

An electromechanical relay is provided with a housing, a relay assembly within the housing, and a data collection cover enclosing the relay assembly within the housing. The data collection cover includes sensing members that extend in toward the relay assembly and engage disconnect switches of the relay assembly. The sensing members transmit analog signals to an analog-to-digital converter that converts analog signals to digital signals. The cover then stores, displays and/or communicates the digital information.
