POSITION INDICATING DEVICE FOR DRAW-OUT TYPE CIRCUIT BREAKER

PROBLEM TO BE SOLVED: To provide a position indicating device for a draw-out type circuit breaker capable of indicating the position of a breaker unit reliably. SOLUTION: An operating plate 37 is provided that is locked by the locking piece 29 of a draw-out frame on the base plate 35 mounted on the breaker unit in such a way as to be freely slidable. An indicator 33 is provided on the arm of an operating lever 38 provided with an actuating pin 42 that engages the operating groove 44 of the actuating plate. The groove 44c of the operating plate 37 that the operating pin 42 engages while the breaker unit moves at a testing position is formed in such a way as to cross at nearly right angles in the moving direction of the breaker unit, compared with the groove 44b for the movement of the breaker unit between the breaking position and the testing position and the groove 44d for the movement of the unit between the testing position and a connecting position.
