Designed to initiate a high-explosive munition of the ZAL type at the moment of impact after being dropped from an unmanned aerial vehicle.
The fuse is an inertial mechanical device of push action. After the ammunition hits, the inertial movement of the striking mechanism ensures the initiation of the installed KD-8A detonator capsule.
The fuse is attached to the ammunition from the stabilizer side. The KD-8A detonator capsule is inserted into the fuse channel until it stops and is fixed before combat use.
