<p>The present invention includes a load break switch. A load break switch (100) includes a break switch part (110) which switches a load current, a power fuse (150) which blocks an overload current and a short circuit current, and a ground switch (130) which simultaneously grounds the input terminal and the output terminal of the power fuse in opening the break switch part. The ground switch includes a fixing electrode (133) for input which is arranged between the output side of the break switch part and the input terminal of the power fuse, a first fixing electrode (135) for ground which is arranged between the input terminal of the power fuse and a ground terminal, and a second fixing electrode (137) which is arranged between the input terminal of the power fuse and the ground terminal. The fixing electrode for input, the first fixing electrode for ground and the second fixing electrode for ground are arranged in the same center axis (O). A moving electrode moves straightly along the center axis in the fixing electrode for input, the first fixing electrode for ground, and the second fixing electrode for ground, thereby allowing the state of the load break switch to be selectively changed into an input state, an opening state, and a ground state.</p> |
