示装置。A heat deformable element whose base end is fixed to an outer frame attached to the circuit breaker case body, a gear rotatably attached to a pin implanted in the outer frame, a gear that rotates coaxially with the gear and one side of which is the gear. a latch arm whose other side engages with the movable tip of the thermally deformable element; a return spring which returns the latch arm to a normal position when the thermally deformable element returns;
It is characterized by comprising a stopper that keeps the gear at a stepped position, and a display plate that moves together with the gear, and displays the remaining life of the circuit breaker based on the operation history such as the operation stroke and number of operations of the heat deformable element. A device that indicates the life of a circuit breaker.
