The Underwater Time Delay Fuses UTDF-2B and 3M are designed to initiate various types of underwater charges.
The fuse UTDF-2B contains RDX and is intended for a direct detonation of underwater charges. It can detonate a charge placed behind a steel plate up to 20 mm thick. An adapter consisting of magnets ensures the stable fixation to the target.
The fuse UTDF-3M initiates a “Nonel” shock tube detonator through Primer No 8.
Each fuse is provided with a soluble transportation safety lock, which ensures safety during assembly and programming.
