REMOTE CONTROL RESIDENTIAL CIRCUIT BREAKER

REMOTE CONTROL CIRCUIT BREAKER SYSTEM

A remote control residential and commercial circuit breaker system (320) provides overload current protection and load management. The system includes a plurality of remote control circuit breakers (20, 322) each including a switch (188, 190, 150, 152) responsive to a control signal (330) for controllably completing and interrupting a respective load circuit (184), a plurality of pole controllers (336, 338) each responsive to a respective address signal (342, 344) and coupled to a respective circuit breaker and supplying the respective control signal to the respective switch. Each pole controller includes a status circuit responsive to actuation of the switch and supplying a status signal indicative thereof. A common controller (348) is coupled to the pole controllers and supplies addresses signals.

DUAL BAFFLE APPARATUS FOR ELECTRICAL SWITCHING DEVICE

A baffle for use in a circuit breaker includes a first baffle mechanism and a second baffle mechanism. Each of the first and second baffle mechanisms includes a base, a plurality of elongated members supported by the base, and cro ss-pins or other elongated members for supporting the base of one of the baffle mechanis ms substantially parallel to the base of the other baffle mechanism. The elongated members of the first and second baffle mechanisms are interleaved to form a laby rinth.

MAGNETIC LATCH ATTACHMENT WITH RELAYS

ADAPTER PROVIDING UNITARY MOUNTING CAPABILITY FOR STANDARD CIRCUIT BREAKER

An adapter converting a standard plug-on, bolt-in power distribution panelboard type circuit breaker for use in industrial control applications comprises a molded insulating base having a rail engaged by a hook of the circuit breaker and a conductor having a first terminal compatible with the circuit breaker terminal and a second terminal comprising a wiring connector. The adapter is mountable to a panel or within an enclosure, flat against a panel or on a DIN rail or is attached to the breaker when the latter is front-mounted to a door or panel. A snap-on catch for mounting plate and DIN rail mounting is deflectable by an attached breaker to pinch the grip of the catch on the plate or DIN rail to prevent lateral movement, and by a screwdriver or the like from the front to release the base from the plate or rail. The plate accommodates plural bases in ganged relation to provide multiple capability mountable as a unit.

Dual baffle apparatus for electrical switching device

A baffle (212, 250, 252) for use in a circuit breaker (20', 20) includes a first baffle mechanism (204, 250) and a second baffle mechanism (206, 252). Each of the first (204, 250) and second (206, 252) baffle mechanisms includes a base (214, 224, 258, 270), a plurality of elongated members (208, 210, 264, 266) supported by the base (214, 224, 258, 270), and cross-pins (220, 222, 230, 232) or other elongated members (264, 266, 276, 278) for supporting the base (214, 224, 258, 270) of one of the baffle mechanisms (204, 206, 250, 252) substantially parallel to the base (214, 224, 258, 270) of the other baffle mechanism. The elongated members (208, 210, 264, 266) of the first (204, 250) and second (206, 252) baffle mechanisms are interleaved to form a labyrinth (280, 282).

REMOTE-CONTROL-TYPE HOUSE CIRCUIT BREAKER

PURPOSE: To facilitate housing of contacts in a narrow case and enable both overload current protection and load control by providing plural sets of contacts, a tripping mechanism part, an actuator, and a feedback means. CONSTITUTION: A first set of contacts comprises a pair of separable overload breaker contacts 44, 46. A tripping mechanism part and a switch which separate the contacts 44, 46 from each other when an overcurrent flows are provided, and a second set of contacts comprises a pair of switching relay contacts 150, 152 electrically connected in series with the contacts 44, 46. An actuator 154 operates the contacts 150, 152 mechanically when excited, and a feedback means showing the conditions of the contacts 150, 152 in response to the excitation of the actuator 154 is provided. Thus the operating force of the actuator 154 is reduced and its size can be reduced, whereby the contacts 44, 46, 150, 152, and the like can easily be mounted in a narrow case and the condition of load ...

CIRCUIT BREAKER

PROBLEM TO BE SOLVED: To provide a circuit breaker wherein a trip coil is used as a shunt resistor which is connected in parallel to a current-limiting polymer element. SOLUTION: A trip unit constituted of a solenoid 34 is connected in parallel to a current-limiting polymer element 32 which is connected in series to a contact 36 of a circuit breaker and acts as a shunt resistor of the current-limiting polymer element 32. When the current-limiting polymer element turns to the state of high resistance which is caused by short-circuit trouble, the trip unit is energized, the contact is opened, and the circuit breaker is tripped. A solenoid 34 formed by winding a resistance wire is preferable. COPYRIGHT: (C)1998,JPO ...
