The 6000 A Icn at 230 V (per EN/IEC 60898-1) is the domestic-grade rating; for industrial distribution you'd size on the 60947-2 figure. It's rated for isolation (both standards), so you can use it as a disconnecting means downstream of a main switch.
The 36 mm width (4 x 9 mm pitches) and 78.5 mm depth fit neatly into a distribution board — no overhang past the rail.
