Abstract:
A circuit breaker includes a housing having a bottom containing a first cavity, a second cavity and a trip mechanism disposed in the housing. A first terminal is electrically connected to the trip mechanism and located in the first cavity and a second terminal is electrically connected to the trip mechanism and located in the second cavity. A first terminal barrier is connected to the housing and is movable from a first position covering the first cavity to a second position at least partially exposing the first cavity and a second terminal barrier is connected to the housing and is movable from a first position covering the second cavity to a second position at least partially exposing the second cavity.
Abstract:
A circuit breaker assembly includes a plurality of circuit breakers each including a housing with a trip mechanism therein and each having an opening in a side of the respective housing. Each trip mechanism has a coupler disc connected thereto. The plurality of circuit breakers are aligned in an end-to-end fashion with a trip member positioned along a side of the housings and connected to the coupler discs such that if the first trip mechanism actuates from a untripped state to a tripped state the trip member actuates the second trip mechanism from a untripped state to a tripped state and vice versa.
Abstract:
A circuit breaker having a movable contact arm for opening and closing the circuit which is controlled separately by a circuit breaker mechanism for circuit protection and by a switch lever mechanism which does not require actuation of the circuit breaker mechanism to function. The switch lever may be activated by a solenoid or other suitable means, and various interlocking mechanical states exist among the elements that provide added safety features.

Abstract:
A circuit breaker includes a shielding component having an external portion which defines a space external to the circuit breaker housing and covers a vent in the circuit breaker housing to direct gasses and debris from the vent to an outlet. The external portion also prevents insertion of the circuit breaker into a breaker box closer than the distances defining the space. This can have the advantage of preventing arcing from the breaker contacts to the breaker box. The external portion may also prevent insertion of the circuit breaker into a breaker box such that a vent in the circuit breaker housing is blocked. In some implementations, the shielding component contains an internal portion which extends into the circuit breaker housing and is disposed to impede debris generated by contact arcing, or other debris, from entering the mechanism of the circuit breaker.

Abstract:
A circuit interrupter having a compact design. According to some implementations, the circuit interrupter includes a conductor from a terminal to a contact having a portion that is angled with respect to the housing sides. This allows a fastener sleeve used to secure the device housing to be positioned closer to the center of mass of the housing, reducing the area of the housing. In some implementations, an arc splitter is provided which includes conductive plates that are angled with respect to the housing sides, allowing the area of the housing to be reduced. In some implementations, a terminal is designed to accommodate a connection without being doubled back, reducing the clearance required for the terminal and the overall area of the circuit interrupter.
Abstract:
A rocker switch having a housing and a rocker extending from the housing. The rocker has a first side with a first end and a second end, a second side adjacent to the first side, and a channel. The channel is disposed on the second side of the rocker and has a first end and a second end. A pivot point is disposed on a crank. A pin, disposed on the crank, is located in a first side of the channel. The depression of the first end of the rocker causes a rotational movement of the channel in a curvilinear path around the pivot point, causing a rotational movement of the crank, moving the pin from the first end of the channel toward the second end of the channel.
Abstract:
An electromagnetic circuit breaker assembly, comprising at least one circuit breaker, is provided with a reverse polarity circuit that reduces the voltage presented to the terminals of the circuit breaker to which it is electrically connected when the terminals are further connected to a source of voltage in reverse polarity. The circuit breaker assembly is tripped due to the reverse polarity set-up, and remains tripped until the polarity is corrected. The electromagnetic coil is continuous provided with sufficient voltage so that the breaker may not be manually reset until the polarity is corrected. Preferably, the breaker is mechanically connected with another circuit breaker to create an assembly that will protect circuitry and devices against both a reverse polarity condition and an overload condition under normal operation. To this end, the reverse polarity circuit does not affect operation of the circuit breaker assembly if the polarity is in accordance with the normal set-up.
Abstract:
A low profile mounting bracket carries coupling connector blocks that mate with load and line terminals of a molded split case circuit breaker housing. The housing defines a well for receiving an alarm or auxiliary switch, and the switch is received in a central opening in the bracket with the switch terminals in turn received in a connector that fits into the same central opening. Finally, a PC board is used to electrically connect each switch to external circuitry that may generate alarms or otherwise affect the circuit breaker's operation.
