Claims

[Scope of utility model registration request]

(1) A stator that has a fixed contact at one end, a movable element that has a movable contact that faces the fixed contact at one end, and the other end of the movable element whose intermediate part is rotatably supported on a fixed object. A link rotatably supported at one end and having a long hole extending from one end to the other end, an intermediate portion rotatably supported on a fixed object, and an inner end rotatably engaged with the other end of the link. an operation handle having a protrusion in the molded case corresponding to the opening of the molded case; and an operation handle that engages with the movable element and switches the switching contact when the movable contact is separated from the fixed contact. a limit switch that switches from a first terminal to a second terminal;
, an operation switch that switches and connects a second terminal to an external power source, an electromagnetic device having a coil connected to a switching contact of the limit switch and a movable iron core that is attracted when the coil is energized, and one end of which is connected to the link. A remotely operated circuit breaker comprising a connecting body that is slidably engaged in an elongated hole and whose other end is rotatably supported by the movable iron core.

(2) The remote-controlled circuit breaker according to claim (1), wherein a transparent cover is fitted into the opening.
