Summary:PURPOSE:To ensure an insulating distance and allow a safe mounting even if the width of a bulkhead for partitioning terminal devices is minimized when an equipment body has the same size to various rated currents. CONSTITUTION:On a bulkhead 23 for partitioning terminal devices of plural poles of a circuit provided on the end part of the equipment body 2 of a circuit breaker for opening and closing a circuit by a handle 1 operation and breaking it in response to an abnormality of the circuit, a vertical mounting hole 4 is provided with a taper 41 extending upward being provided on its upper end. The screw head part 51 of a mounting screw 5 spirally fitted to a mounting plate 6 through the mounting hole 4 is received in a bottomed cylinder 7 through which the mounting screw 5 placed on the upper surface of the bulkhead 24 to form a projection 72 fittable to the taper 41 on a bottom part 71 is passed. The upper end 74 of the bottomed cylinder 7 is extended about near the arranging position of a front panel 81 for exposing the handle 1 when received in a board 8.
