摘要： An overload release includes a bimetallic element, a tripping slide, a latch and an energy store. In an overload situation the bimetallic element actuates the tripping slide; as a result, the tripping slide actuates the latch, and as a result, the latch allows the movement of the energy store. The latch is provided with a latch area and the energy store is provided with a latching area, the two areas mechanically interacting in the latched state and the latch area being released from the latching area in the unlatched state, when there is an overload, to allow the movement of the energy store. Further, the latch area or the latching area includes a projection.

摘要： This invention discloses a low-voltage circuit breaker with a capability of tripping quickly. Its main feature is that at least one of the side faces of the contact device provides an open flange which has an internal through hole, and the bottom of a rotating shaft disposed on the bottom part provides a stressed member. The stressed member receives the over-pressure airflow escaping from the open flange of the contact device to generate a force. The force is passed to the activating member by the rotating shaft and is magnified, then hits the latch quickly and makes a trip. An intermediate step is bypassed due to the force produced earlier, the force which is produced by the electromagnetism part in the heat energy and electromagnetic system, so that the low-voltage breaker can open quickly and reduces opening time greatly and improve the breaking capability.

摘要： A remotely controllable circuit breaker with an improved space saving structure comprises first and second movable contacts 11 and 12 which are held respectively on first and second contact arms 31 and 32 and are driven individually by a switching mechanism 20 including a manual handle 22 with a contact tripping capability and by a remote control signal responsive electromagnet 60. An L-shaped actuator 80 with a horizontal member 81 and a vertical member 83 is provided to operatively connect the second contact arm 32 to an axially movable core 63, the output member of the electromagnet 60. The actuator 80 is pivoted at its connection between the horizontal and vertical members 81 and 83 and carries the second contact arm 32 on its vertical member 83 for pivotal movement of the second contact arm 32 between operative and inoperative positions respectively enabling and disabling the contact closing. The electromagnet 60 is arranged in side-by-side relation to the switching mechanism 40 with the first and second contact arms 31 and 32 interposed therebetween. The actuator 80 is located in proximity to the electromagnet 60 with the vertical member 83 extending over the lengthwise dimension or the axial direction of the core 63 and with the horizontal member extending over the width dimension of the electromagnet 60 to thereby accommodate the substantial portion of the actuator 80 within the lengthwise and widthwise dimensions of the adjacently disposed electromagnet 60.

摘要： The disclosed circuit interrupter comprises a magnetic core structure including a magnetic core and magnetic yokes defining an annular magnetic gap around the core, and a primary and a secondary coil wound on the core to form a current transformer. The movable contact arm is disposed in the magnetic gap to be magnetically driven to the open position, and a magnetic armature of an instantaneous trip means is disposed adjacent to the magnetic yokes so that it is magnetically actuated upon a short-circuit current. A bimetallic element of a thermally responsive trip means is electrically connected to the secondary coil of the transformer. The magnetic yokes include extended portions which serve as magnetic means for driving an electric arc established between the separated contacts into an arc extinguisher which is also disposed between the magnetic yokes.

摘要： A circuit breaker has a bistable snap-acting mechanism including a bimetallic arm which renders the circuit breaker capable of actuation by either ambient temperature changes or temperature changes generated internally, as by an excessive electric current. An electromagnetic arrangement enables essentially instantaneous actuation in response to an electric current of predetermined amplitude greater than the excessive current which otherwise might actuate the circuit breaker thermally. An actuating lever assembly includes an actuating lever coupled to a link which is normally latched and is unlatched in response to movement of the bimetallic arm, and enables manual actuation, as well as manual reset of the circuit breaker.

摘要： A distribution transformer having a secondary circuit breaker utilizing a movable bridging contact between two stationary contacts for completing a series circuit therethrough. The movable bridging contact is spring biased towards an open position separated from the stationary contacts, but with the circuit breaker in the normally closed position is held in engagement with the stationary contacts by a latching mechanism which is responsive to a bimetal or magnetic trip element to allow the circuit breaker to trip open during overload conditions. The conducting bridging contact completes a series circuit through the circuit breaker which opens during circuit interruption. The secondary circuit breaker can also, if desired, be provided with a signal-light circuit which activates a signal light, on the exterior housing of the transformer, when current through the circuit breaker exceeds a low signal overload value which is less than the trip value. The signal light circuit is reset by turning the operator handle, which is located on the transformer housing, past the on position away from the off position. An emergency overload control is provided for increasing the tripping level of the circuit breaker during selected overload periods. The bridging contact is disposed near the end of an elongated operating arm which is linked to the circuit breaker operating mechanism. A plurality of poles are operated utilizing only one operating mechanism by connecting the elongated operating arms with a strong metallic member for simultaneous operation of all poles. The single signal light provided for each multi-pole circuit breaker can be activated by the bimetals of any one of the individual poles.

摘要： An improved circuit breaker comprises means operating, when the contacts are welded closed and the cradle is released, to block the trip member or cradle against movement to a reset or relatched position and to maintain the operating handle in the closed position to thereby provide a true external indication of the closed condition of the contacts. The blocking means on the cradle strikes the contact arm in an opening direction when the cradle is released and the contacts are welded whereby if the weld is not firm the striking action will break the weld and open the contacts.
