It snaps onto 35 mm DIN rail per DIN EN 60715 and accepts screw-type terminals on the main circuit — rated for 2x 1…35 mm² or 1x 1…50 mm² solid or stranded conductors, with M6 main contact bolts.
Breaking capacity and trip class
Phase failure detection and ambient range
Built-in phase failure detection is standard — if one line drops, the breaker trips, preventing single-phasing damage. No ground-fault detection on this variant, so plan a separate GF module if the application requires it.
Mounting clearances and dimensions
Dimensions are 55 mm wide, 140 mm high, 149 mm deep. Mounting position is unrestricted, which helps in tight retrofit enclosures.
