Circuit breaker having line terminal and associated indicating method
A line terminal is for an electrical switching apparatus. The electrical switching apparatus includes a stationary contact and a movable contact structured to move into and out of engagement with the stationary contact in order to close and open the electrical switching apparatus, respectively. The line terminal includes a lip portion structured to be connected to the stationary contact in order to provide an electrical pathway therebetween; an arm portion extending from the lip portion, the arm portion having an engaging portion structured to receive and engage a conductive post member and provide an electrical pathway between the conductive post member and the stationary contact; a neck portion extending from the arm portion; and a tab portion extending from the neck portion and being located internal with respect to the engaging portion.
SWITCHING DEVICE AND SWITCHING DEVICE ARRANGEMENT
A switching device having a housing and a contact carrier which is pivotable about a rotational axis, the rotational axis being in particular fixed to the device or the housing, the contact carrier comprising at least one coupling contact for producing or opening a power- and/or signal-carrying contact connection with at least one attached switching device.

AUTOMATIC SECONDARY PLUG FOR INTEGRATED RACKING ON BREAKER
A circuit breaker with an integrated motorized racking mechanism, automatically provides electrical power to the racking motor when the breaker is inserted into a breaker compartment. The racking motor remains powered when the breaker is in either a disconnected position, a testing position, or a fully connected position. A racking power plug mounted within the circuit breaker conducts electrical power to the racking motor by automatically connecting to a stationary racking power receptacle mounted in the breaker compartment, and remains connected as the circuit breaker moves through the breaker compartment during the racking operation. A control power plug is mounted in the circuit breaker to connect to a stationary control power receptacle mounted in the breaker compartment and to conduct control power to control circuits in the circuit breaker after the racking motor has completed racking the circuit breaker into the connected position in the breaker compartment.

Power distribution assembly
A power distribution assembly that includes a planar substrate, a set of switchable elements arranged on the planar substrate, a conductive bus bar underlying the planar substrate and interconnected with the set of switchable elements, and a set of power connections. The power distribution assembly distributes power from a power source to one or more loads.
Fuse Holder
A fuse holder provides a safe device for connecting fuses to a three-phase busbar device. Each phase includes a corresponding load conductor and line conductor mounted within a housing. A mechanical lock is provided for each phase that locks a knife of the fuse to one of the conductors for the phase. In a further aspect, the fuse knives are frictionally locked within the housing. In both the mechanical lock and frictional lock, a release mechanism is provided that can be activated by a screwdriver to release the fuse knives from the fuse holder. In another aspect, certain conductors are provided with heat dissipation wings that contact the housing to dissipate heat generated by current flowing through the conductor.
Integrated electrical panel
The system includes one or more busbars couple to an AC line, branch relays each coupled to a busbar and to a respective circuit breaker, and current sensors each corresponding to at least one respective branch relay of the plurality of branch relays. The system also includes a deadfront arranged in front of the plurality of branch relays, and including openings corresponding to the branch relays allowing an electrical terminal of each branch relay to protrude forward through a respective opening. A circuit breaker is engaged with each respective branch relay, on the deadfront to create an array of branch circuit breakers. The combination of relay and circuit breaker allows each branch circuit to be controllable. The relays may include current sensors, such as a shunt, used to determine a branch circuit current and control the relay. Control circuitry manages the relay on-off operation and monitors branch circuit operation.
BUS BAR SYSTEM WITH AT LEAST ONE BUS BAR HELD IN A CONTACT PROTECTION HOUSING
A bus bar system having at least one bus bar which is accommodated in a contact-protection housing in a contact-protection manner and in an accessible manner via contacting passages for electrical devices and/or device adapters, the contact-protection housing having a lower part and an upper part which is detachably fixed on the lower part and between which the at least one bus bar is held, wherein the upper part has, on its side facing the lower part, a plurality of plug-in receptacles extending from the latter into the lower part, and the lower part has at least one slide with at least one latching pawl which can be adjusted between a locking position, in which the at least one latching pawl engages in the plug-in receptacle, and a release position, in which the at least one latching pawl is positioned in front of the plug-in receptacle. A corresponding method is further described.
PLUG-ON NEUTRAL DEVICE AND KIT
A plug-on neutral (PON) device includes a housing that defines a phase cooperation portion configured to physically cooperate with phase buses of a bus assembly. The phase cooperation portion is configured to be electrically isolated from the phase buses and stabilize the PON device when installed on the bus assembly. A neutral cooperation portion is configured to physically cooperate with the neutral bus and to physically stabilize the PON device when installed. An electrical connector disposed at the neutral cooperation portion is configured to electrically connect to the neutral bus at an external end and to electrically connect to a conductive current path at its internal end. A lug assembly has one or more conductive terminal lugs, each terminal lug configured to receive current from an external neutral source via an aperture in the lug end of the housing and to electrically connect to the current path.
