Three poles protected, toggle-operated, rated for distribution duty per EN/IEC 60947-2. The TM-D trip gives you L (thermal overload) and I (magnetic short-circuit) protection in one block — no add-on modules needed for basic feeder or branch protection. At 50 A and 40 °C ambient, it's sized for a 50 A continuous load without derating; push it above that and you'll need to consult the thermal curve. Breaking capacity is the headline here: 70 kA Icu at 415 V AC, 100 kA at 240 V, and still 35 kA at 525 V. The 10 kA at 690 V tells you this frame isn't meant for 690 V primary distribution, but it'll clear a fault there if needed.
Front connections both top and bottom, with a 35 mm connection pitch that matches standard busbar systems. IK07 impact rating means it'll survive a dropped tool during commissioning.
Electrical durability is 50,000 cycles at 440 V In/2, 30,000 at full rated current, and 10,000 at 690 V. Mechanical durability matches at 50,000 cycles. That's a solid maintenance interval — plan for contact inspection around those counts, not before. Power dissipation is 4.11 W per pole, so about 12.3 W total at full load. That's low enough to skip forced cooling in a ventilated enclosure, but cluster several of these and you'll want to check the internal temperature rise. No earth-leakage protection built in; add a Vigi module separately if you need GFCI.
