Claims

[Claims for Utility Model Registration] (1) In a circuit breaker having an overcurrent detection device and a tripping latch operated by the overcurrent detection device, the tripping latch is set to the tripping position. A manual trip lever inserted into the frame so as to be slidable between a latch operating position in which the latch is activated and an inoperative position in which the tripping latch is not activated, an operation window for the manual trip lever provided in the frame, and the manual trip lever A circuit disconnector characterized in that a display such as "Inspection" is provided on an exposed portion of the manual trip lever that is exposed from the operation window when the manual latch is in the manual position. (2) The manual trip lever includes a slide plate that is slidably inserted into the frame, a manual operation section that is provided on one side of the slide plate and projects out of the frame from an operation window, and a manual operation section that is provided on the other side of the slide plate. A circuit breaker according to claim 1, which is comprised of a latch engaging protrusion that engages with a tripping latch. (3) The circuit according to claim 2 of the utility model registration, in which a protrusion is provided at the end of the slide plate, and recesses are provided in the frame, into which the protrusions fit into the manual trip lever's latched position and non-operated position, respectively. Shiya disconnector.
