FUZE Features
· Completes ammunition for both rifled and smooth-bore guns.
· Ensures round ignition on hitting target positioned within 1.500 m of the muzzle.
· Delayed action allows the round to pass through target shield and to explode behind.
· The fuze guarantees self-destruction of the round within 3.500 m from the muzzle.

Fuze Safety
Before firing the Safety and Arm device prevents the detonator from positioning into the fire train. Even in case of unintentional ignition of the primer, no transfer of the firing pulse to the fire train can occur.

Fuze arming
The fuze is armed within 5 to 20 m from muzzle. At firing the set-back forces arm the fuze, fixing the elements of the fire train in one line.

Upon impact, the fuze provides delay of 0.02 sec.

In case of no impact the round is self-destruct within 3.5 to 6 s.
