More like NxRA. I remember that in a patent by Rafael (patent number US 7,360,479 B2) they were explaining the advantages of newer types of reactive armors and listed both NxRA and SLERA as the best compromises between ERA threat defeat and NERA multi shot capability (with NxRA being better in this regard). I guess that in theory you could optimize NxRA to either release all its energy contained in its energetic materials in a single instance (thus working like an ERA tile) or across several shots, thus working more like NERA.
Also i remember this article http://igorrgroup.blogspot.com/2010/06/russian-nxra-for-lavs.html?m=1 stating that reactive armor based on energetic materials was being explored by the russians for some time:
"An attempt to raise the efficiency of the reactive armor led “NII Stali” to creation of so called energetic materials. Energetic materials are a new class of protective materials, which stands between conventional ERA and reactive armor. R&D conducted in “NII Stali” has shown that when the shaped charge jet impacts the energetic material enclosed between metal plates, in the interaction zone which is as small as 60-120mm, a chemical reaction takes place with release of a considerable amount of energy. The energy release rate is comparable to that of the best plastic explosives. It’s about 5000m/s in the interaction zone, and decreases to sonic speeds with the distance from the epicenter. It prevents the shift of the process to the stage of the steady-rate detonation. The efficiency of such systems is much higher than that of other reactive armor systems discussed above, because all the energy released in the local zone is directed to destruction of the shaped charge jet...
This type of reactive armor is called NxRA abroad, which means it doesn’t use any explosives; it’s used in a variety of different armor systems (SLERA, LRA, IRA etc.). The use of this approach in reactive armor designs with multi-row cluster order of energetic elements with different levels of energy release allows control of the interaction process and adaptation to particular parameters of the shaped charge jet, which results in increased protection. Energetic materials can be based on different formulations. Due to selective sensibility to the shaped charge jet energy, the energetic materials are effective against tandem-warhead rounds and long-rod penetrators of APFSDS.The ideas of such hybrid reactive armor abroad are implemented only for protection against single-warhead chemical energy projectiles and kinetic-energy projectiles of small-caliber guns. Russian designers are pursuing more ambitious goals for hybrid reactive armor, and they are very close to creation of really multipurpose systems that provide protection against the complete range of threats, including tandem projectiles."
