NT-26 cartridge is intended for an individual cover / passive defense of an aircraft (aircraft or helicopter) prior to hitting directed air-to-air or surface-to-air missiles, equipped with self-guiding heads for infrared radiation sources as its emitters are usually hot engine exhaust nozzles / engines.

The cartridges are fired from special devices called BWP-30-26 or ASO-2 ejector cartridges (in a colloquial language also called flare and dipole ejectors).

The firing of cartridges (in series) takes place in the event of a threat to the aircraft.

The cover is realized by creating an apparent thermal target or otherwise a thermal trap which emits strong heat radiation with maximum energy in the 3-5 μm wavelength range, with an initial power of not less than 1 [kW] for a minimum period of 3 seconds.

Burning thermal elements disrupt the thermal field near the aircraft, concealing its thermal signature, reducing or even preventing the risk of directly hitting the missile (performing evasive maneuvers at the same time).

Piotr, thanks a lot for this info!
Is there maybe a photo of the headstamp and primer?
