    摘要: A remote-controlled circuit breaker has an operation mechanism unit, for selected one of an off state and a remote-controllable state of the circuit breaker, and a movable contact which makes/breaks contact with a fixed contact in connection with a motion of an electromagnetic unit only in the remote-controllable state; and the movable contact breaks contact with the fixed contact irrespective of the motion of the electromagnetic unit at the time when an overcurrent tripping unit is operated by a fault. A push rods acts in conjunction with a transmission lever to either provide an indication of the state of contact connection or to actuate tripping. An indication mechanism is also disclosed.

    摘要: A remote-controlled circuit breaker has an operation mechanism unit (300), for selecting one of an off state and a remote-controllable state of the circuit breaker, and a movable contact (11, 12) which makes/breaks contact with a fixed contact (9.16) in connection with a motion of an electromagnetic unit (200) only in the remote-controllable state; and the movable contact breaks contact with the fixed contact irrespective of the motion of the electromagnetic unit at the time when an overcurrent tripping unit (400) is operated by a fault. A control lever (63) for moving the movable contact into and out of contact with the fixed contact has an elastic element (63A) which strengthens the engagement of a latch mechanism in the overcurrent tripping unit during an off-time of the electromagnetic unit.

    摘要: A remote-controlled circuit breaker has an operation mechanism unit (300), for selecting one of an off state and a remote-controllable state of the circuit breaker, and a compact electromagnetic unit (200) and a movable contact (11, 12) which makes/breaks contact with a fixed contact in connection with a motion of the electromagnetic unit only in the remote-controllable state; and the movable contact breaks contact with the fixed contact irrespective of the motion of the electromagnetic unit at the time when an overcurrent tripping unit (400) is operated by a fault.

    摘要: A remotely operated circuit breaker comprises a handle which is selectively positioned at one of three operating positions: a handle off position into which the handle is manually positioned to forcibly open the electrical contacts in the circuit breaker; a handle auto position into which the handle is positioned manually so that the electrical contacts are driven to normally open and close by a control mechanism which in turn is controlled by an electromagnetic driving unit response to a remote control voltage applied thereto; and a trip position into which the handle is automatically positioned by the control mechanism and a forcible overcurrent protecting unit to and the electrical contacts are opened rapidly when an overcurrent as well as a short-circuit current flows through the electrical contacts.

    摘要: A circuit interrupter comprising a pair of separable contacts at least one of which is movable, and an operating mechanism operatively connected to the movable contacts for opening and closing the contacts. The operating mechanism includes a movable contact arm having mounted thereon the movable contact, a latch lever pivotally mounted on the movable contact arm, and a toggle link mechanism connected at its one end to an operating handle and the other end of which is directly engageable with said movable contact arm and the latch lever. The movable contact arm has a latch surface, and the latch lever has a latching end which, in cooperation with the latch surface, releasably catches the other end of the toggle link mechanism. The operating mechanism further comprises a yieldable member providing a yieldable stop surface for preventing the automatic return movement of the other end of the toggle link mechanism from an extended position after the trip operation to a reset position and for yieldably maintaining the other end of the toggle link mechanism at a position in which the toggle link mechanism is partly collapsed. The yieldable stop surface can be overcome by the manual moving effort on the operating handle.
