О-4N FUZE

The О-4N fuze is intended for use on ОG-7, ОG-9 fragmentation grenades, and  60mm, 81mm and 82mmmortar bombs. This fuze is a nose impact type with two settings – forinstantaneous (fragmentation) and inertial (HE) action, with distant arming and a semi-boresafe explosive train.

A design element is introduced for manual activation of the fuze safety feature with a view to increase the safety in handling  – during transportation, loading-unloading operations, after accidental dropping, and during airborne landing up to the moment of firing the ammunition.

The O-4N fuze coming with ammunition packed in cases, is safe in handling, during transportation and after accidental dropping from a height of 12 m in any orientation.
