Rated breaking capacity hits 100 kA at 240 V, 400 V, 500 V, and 690 V AC — meaning it can safely interrupt a fault up to that level without upstream fuses needing to clear first, which simplifies coordination in a distribution panel.
Width is 45 mm, depth 97 mm, height 106 mm — a compact 45 mm footprint for a 100 kA rated device, leaving room for adjacent breakers or contactors on the same DIN rail. Clearance requirements: 50 mm upwards and downwards, 30 mm at the sides, 0 mm forwards and backwards — so you can pack it tight front-to-back but need breathing room top and bottom for arc exhaust.
