Even if the fuse fuses it 1 phase it opens three-phase be simultaneous. Therefore there is not the care of an absence phase.
Fuse replacement is produced safely due to the structure that does not open if the bottom cover does not do the handle to "earnest".
Also I do not require a special tool including the hook stick when I replace the fuse. It is possible easily with safe gloves.
Pulling out it even if the handle is fixed in the input position because it is a handle free ceremony actuation is possible.
