POSITION INDICATING DEVICE FOR PULLOUT TYPE CIRCUIT BREAKER

PROBLEM TO BE SOLVED: To provide a position indicating device for pullout type circuit breaker which can surely indicate that the main body of a circuit breaker reaches a connecting position. SOLUTION: A working plate 37 which is locked by means of the locking piece 29 of a pullout frame is slidably provided to a base plate 35 attached to the main body of a circuit breaker and an indicator 33 is attached to the arm of a working lever 38 provided with a working pin 42 engaged with the working groove 44 of the working plate 37. Until the main body of the circuit breaker reaches a connecting position, a position indicating device detects the sliding amount of the working plate 37 relatively to the base plate 35, namely, the moving amount of the main body and the working lever 38 rotates. After the main body reaches the connecting position, a connecting rod 26 largely rotates the working lever 38 by pushing the working pin 42 relatively moved to the right end section of a groove 44e to the left end section of the groove 44e through an operation enlarging lever 39 and a push lever by pushing up an enlargement actuator 46.
