PROBLEM TO BE SOLVED: To prevent erroneous connection in the case of providing a plurality of load side terminals capable of outputting different voltages. SOLUTION: This circuit breaker 1 is constituted by providing the upper face of a case 2 with an operating handle 3 for opening/closing an electric line, and arranging power supply side terminals 4 on the front face of the case 2 and the load side terminals 5 on the back face. The case 2 is composed of a pair of divided bodies 20, 21 formed by laterally bisecting other four faces in a vertical direction along a centerline to include right and left side faces respectively. A seal cover 8 comprises insertion parts 10 inserted in terminal holes 15 of the load side terminals 5, and a stopper part 11 connected to the insertion parts 10 to prevent the insertion parts 10 from being inserted in the terminal holes 15 to a predetermined depth or deeper. Both longitudinal ends of the front face of the case 2 are provided with locking parts 12 formed in inverted L-shape cross section and locking to press both long-side ends of the stopper part 11 from the outside.
