Snap-on mounting onto 35 mm DIN rail per DIN EN 50022. 55 mm wide, 140 mm tall, 149 mm deep. Zero clearance required at the back or sides — no extra breathing gap needed for the enclosure cutout. Screw-type box terminals on the main circuit accept 2x (0.75…16 mm²) solid or 2x (0.75…25 mm²) stranded; auxiliary and control circuit uses separate screw terminals.
Rated short-circuit breaking capacity: 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, 4 kA at 690 V AC. Surge voltage resistance rated at 6 000 V.
Power dissipation
19 W total power dissipation in hot operating state; 6.3 W per pole. That matters for thermal rise inside a sealed enclosure — plan the cabinet cooling budget accordingly if you're stacking several breakers in a row.
