It breaks 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, which covers most industrial panel fault levels. The 3-pole, 3-width-unit (54 mm) body snaps onto the DIN rail with the quick-assembly system and accepts conductors from 0.75 up to 35 mm² solid or stranded, so it handles both control-circuit tails and feeder-size cable on the same terminal.
Two breaking-capacity ratings are listed because the standard under which the fault is tested changes the result: 10 kA under EN 60898 (the domestic / light-commercial benchmark) and 15 kA under IEC 60947-2 (the industrial standard that also tests for coordination with upstream devices).
Mounts in any position on the DIN rail. The 54 mm width (3 width units at 18 mm each) and 76 mm depth (70 mm installation depth behind the panel face) fit standard SENTRON cut-outs. Combined terminals top and bottom mean the same box lug accepts solid or stranded copper from 0.75 mm² up to 35 mm² — no adapter needed when stepping from a 4 mm² control wire to a 25 mm² feeder. Sealable for lockout/tagout compliance. Overvoltage category III suits fixed-installation distribution boards.
