Fuse combination boxes
The fuse-switch consists of a combined 3-pole fuse-link base with front operated switch-disconnector function. The cover is interlocked and cannot be opened in the closed position. In the open position, it is energized on both sides of the fuse-link and the switching functions also satisfy the conditions applicable for the disconnector. It is also possible to lock the operating mechanism with a padlock in the closed position. SLBP 3250, 3400 SLBP and SLBP 3630 have two-piece flange openings on the top and bottom. The fuse-switch is also equipped with PE+N.
