It is equipped with a label for description of the protected circuit.

Measuring holes in the cover. Basic design with terminal screws M12/28 Nm for cable

lugs max. ø 44 mm and busbars of width max. 40 mm.Connecting sets with terminal inbus screws.Variability of connecting sets including rear connection.It is possible to lock the switch-disconnector cover.

Mounting: Directly on the panel by means of screws.

On busbars with spacing 60 mm by means of adapter.More switch-disconnectors “side-by-side” or “fl at” can be installed without limitation of electrical parameters.Bottom connection is possible without limitation of electric parameters ( the device should be marked „ATTENTION, BOTTOM CONNECTION“).

Fuse switch-disconnector FH3 is intended for fuse-links with blade contacts size 3. It enables safe disconnection not only of rated current, but also overcurrent up to octuple rated current.

A version of this switch-disconnector enables remote signalling of fuse-state, in each pole separately. For signalling of fuse state is used standard visual status indicators of the fuse-links with blade contacts.

Fuse switch-disconnectors up to 630 A
