Well here is something about ERA
First generation were the israeli ERA brick type blocks which were basic explosives which defeated Heat or other chemical rounds.
Then russian Kontakt-5 which were like the brick ERA but had a thicker denser outside to try break the tip of a APFSDS round and gave it extra protection which was mildly better.
Then there is this new third generation Kaktus type of interweving armour which is a lot thinner and looks like it doesn't contain a lot of explosives or maybe none at all. Im just assuming this is just going to be used to defeat APFSDS rounds
Comparision
As you can see a lot thinner. And possibly the armour arrangment is a clam shell one as well
Here is a good read about ERA

Fofanov does good work. In a nutshell, LancerMc is right about ERA;but it's the flyer plate (a plate of metal that goes flying at an angle to the jet penetration) that disrupts the HEAT jet or deflects the penetrator. First-generation ERA did very little against APFSDS, as Vasily notes on his site, but Kontakt-5 and Kaktus apparently do pretty well.
Ceramic armors are very hard but brittle, which means that they can blunt and/or erode long-rod penetrators. And when they are backed by a very dense material (like DU or tungsten), they can be very effective at stopping penetration because the now-blunted penetrator needs to push a plug of ceramic material through the dense armor. "Composite armor" usually means several layers of different materials, of different densities. These layers can induce yaw in a penetrator and help disperse a CE jet. When ERA is added as the first layer, the KE or CE penetrator is already blunted/yawing/dispersing by the time it reaches the main armor.
