Claims

[Claims for Utility Model Registration] A handle, a movable contact having a movable contact that is brought into contact with and separated from a fixed contact by the handle, an opening/closing operation mechanism disposed between the movable contact and the handle, and the movable A remote-controlled circuit breaker comprising an overcurrent detection device that opens a contactor due to an overcurrent, and an operating electromagnet that controls on and off the handle by a remote control signal, the opening/closing operation mechanism being , a first end slidably and rotatably engaged with an operating pin of the handle;
a second link, one end of which is rotatably connected to the other end of the first link, one end of which is rotatably connected to the other end of the second link, and an intermediate portion of the second link is rotatably connected to the other end of the first link; a movable frame rotatably supported by a first pivot pin; an intermediate portion rotatably supported by a second pivot pin of the frame; and an intermediate portion of the first link at one end rotated by a link pin. and a tripping latch whose intermediate portion is rotatably supported by a third pivot pin of the frame and which removably engages with the other end of the lever; An armature in which an operating electromagnet passes through a central opening of a bobbin around which a coil is wound, with both ends protruding from the bobbin, and the left and right sides of the protrusion serve as suction parts, and a yoke disposed on both left and right sides of the armature. , a permanent magnet provided between the yokes and passing a magnetic flux through the yoke to the armature, and the magnetic flux formed by the coil is superimposed on the magnetic flux of the permanent magnet of the operating electromagnet to cause the armature to pass through the armature. When the handle is reversibly rotated or the handle is manually operated, the first link rotates about the link pin as a fulcrum, and the movable frame is rotated through the second link to the first pivot point. The movable contact of the movable contact is rotated about the support pin as a fulcrum, and the movable contact of the movable contact is connected and separated, and the tripping latch is actuated by the overcurrent detection device and the third
When the lever rotates about the second pivot pin as a fulcrum, the lever disengages from the tripping latch and rotates about the second pivot pin, and one end of the first link slides on the operating pin. In the engaged state, the first link rotates about the operating pin, and the movable frame rotates about the first pivot pin via the second link, so that the movable contact The remote control type circuit breaker is configured to open and release the movable contact of the child, characterized in that an operation link connecting the armature of the operation electromagnet and the operation pin of the opening/closing operation mechanism is formed of an elastic body. Remotely controlled circuit disconnector.
