I finally found some information on Kaktus from a NII Stali booklet, and got lucky because I only found it doing a search for 4S24, since that's the code used by the manufacturer for that ERA's blocks. They report that it's the same effectiveness as 4S20, just with half the explosive. 4S20 is Kontakt-1 (4S22 is Kontakt-5 and 4S23 is Relikt, just for reference). So, 80 points of AV vs HEAT and no additional armor against KE.
