Claims

[Scope of utility model registration request]

(1) It has an opening/closing mechanism that opens and closes the contact by an overcurrent tripping device that is activated by a predetermined overcurrent, and a movable iron core that has a large diameter part and a small diameter part connected to the large diameter part. ,
a voltage tripping device that opens the contactor via the opening/closing mechanism when energized; a first guide portion comprising a through hole into which the large diameter portion of the movable core can be loosely fitted; and a second guide portion consisting of a through hole formed to have a smaller diameter than the large diameter portion and into which the small diameter portion of the movable iron core can be fitted loosely, and when the voltage drawing device is energized, Second
A circuit breaker comprising a display member that is constantly biased in a direction in which the guide portion of the movable iron core is engaged with the small diameter portion of the movable iron core.

(2) Practical use characterized in that the display member has a display button, and when the contact is separated via the opening/closing mechanism by the bias of the voltage tripping device, the display button protrudes to the outside. A circuit or disconnector as claimed in claim 1 of patent registration.

(3) The circuit breaker according to claim 1 or 2, wherein the display member has a pair of sliding parts formed in a convex shape.
