摘要： In the setting operation conducted by the handle 90 which is an operating section, an upper portion of the portion 26a′ of the slidable T-post 26 is pushed by the end portion of the cam 90b, and the slidable T-post 26 is moved. In accordance with the movement of the card 26, the suction cup block 23 is elastically deformed, and the suction cup 23b is held by the body 24 by a holding force of the suction cup 23b. The body 24 is composed of a porous body, and air flows from the ventilation hole 29 into a space formed between the suction cup 23b and the body 24, via the body 24. The slidable T-post 26 is biased ahead by the return spring 27. When the releasing operation is conducted by the handle 90, the cam 90b is rotated, and the end portion of the cam 90b is separated from the end of the portion 26a′ to be pushed. After that, when the intensity of the holding force of the suction cup 23b to the body 24 is decreased lower than that of the spring force of the return spring 27, the slidable T-post 26 is moved ahead, so that the card member 26c pushes up the movable contactor 70.

摘要： A contact device is provided with an additional mass member secured to a movable contactor carrying a movable contact capable of opening and closing contacts with a stationary contact, for providing to the movable contactor a mass acting in a direction perpendicular to longitudinal axis of the contactor. A rolling motion is thereby caused to occur in the movable contactor upon contact closing motion so that the movable contact can be prevented from being fusion-bonded to the stationary contact.

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： 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 includes an arc shearing plate which is driven to thrust between a pair of contacts being separated so as to shear an arc formed therebetween for rapid arc extinction. Included in the circuit breaker is an over-current responsive actuating member which applies an impact to one of the contacts for rapid contact separation in response to a predetermined over-current condition such as caused by a short-circuit. The actuating member is also coupled to the arc shearing plate so as to control the thrusting movement of the arc shearing plate in synchronism with the rapid contact separation, whereby the timing of inserting the plate between the contacts can be easily controlled with respect to that of separating the contacts for achieving rapid arc extinction and providing a high arc voltage and current limiting action.

摘要： A circuit breaker having an arc suppressing means disposed adjacent a contactor section and including a first arc running plate extended from a fixed contactor and a second arc running plate opposed to the first arc running plate. The distance between the both arc running plates on the side close to the contactor section is minimized so as not to cause any spatial short-circuiting to occur. At portions of the both arc running plates defining the minimized distance, magnetic arc driving force motivated by mutually oppositely directed arc currents flowing through the respective arc running plates is increased to a large extent, whereby arc shifting to deion grid of the arc suppressing means can be performed effectively quickly.
