摘要： A thermally-sensitive overcurrent protective relay includes a housing case, a bimetal strip bendable in response to an operating current flowing through a control circuit of the overcurrent protective relay, and a movable contact biased by a spring to form a toggle mechanism operable in response to the bending action of the bimetal. A lever supporting bracket mechanically supports the movable contact at a fulcrum portion and electrically connects the movable contact to a terminal. The terminal is mounted in the housing case to conduct current to the control circuit through a contact spring for electrically connecting the lever supporting bracket. This lever supporting member includes a trip current adjusting mechanism adapted to be rotated at its end portion by turning an adjusting screw for adjustment of the operation current.

摘要： In a high voltage circuit interrupter switch or recloser a single multi-function control actuator is connected to a trip bar for tripping contact operating linkage to effect opening of one or more movable contacts. The control actuator includes a spring biased crank member and a toggle linkage operably associated to permit resetting of the control actuator to its initial position upon effecting movement of the contact operating linkage. The recloser has a switch for energizing a closing solenoid to reclose the interrupter contact. A movable catch is associated with switch operating linkage and is operably connected to the control actuator whereby the control actuator may effect energization of the solenoid to close the interrupter contacts. The control actuator is also connected to a lockout linkage for effecting lockout of the contact operating linkage upon receipt of a control signal when a predetermined number of circuit interruptions have been performed in a predetermined time period.

摘要： An improved remotely controllable circuit breaker comprises a manually operable switching mechanism for opening and closing a single set of first and second contacts, a trip mechanism for opening the contacts upon occurrence of predetermined overload current conditions, and a remotely controllable switching mechanism for selectively opening and closing the contacts in response to a control signal remote from the breaker. The manually operable switching mechanism includes a movable contact arm carrying the first contact to be brought into and out of contacting engagement with the second contact by manipulation of a manual handle. The second contact is operatively connected to the remotely controllable switching mechanism to be driven thereby for movement between an operative position where the second contact is engageable with the first contact and an inoperative position where it is prohibited from being engaged with the first contact independently of the position of the first contact. Accordingly, the remotely controllable mechanism can be entirely isolated from the manually operable switching mechanism when the former is responsive to the remote control signal for bringing the second contact into its inoperative position.

摘要： A circuit breaker comprising two or more sections connected in parallel with each other. Each section of the circuit breaker comprises an electromagnetic sensing device and a pair of relatively movable contacts. The electromagnetic sensing devices are electrically connected at one of their ends to the load terminals. The load terminals are electrically connected in parallel with each other. The electromagnetic sensing devices are electrically connected at their other ends to each other and are electrically connected to all of the movable contacts which are themselves all electrically connected together. The stationary contacts are connected to line terminals which are also electrically connected in parallel with each other. Thus, the electromagnetic sensing devices are connected in parallel at both of their ends and the relatively movable contacts are also connected in parallel at both of their electrical ends while the electromagnetic sensing devices, on the one hand, and the movable contacts, on the other hand, are also in series with each other, whereby the current is divided equally among all of the electromagnetic sensing devices even though the current may not be equally divided among all of the relatively movable contacts, because of varying contact resistances.
