Rated 880 V DC with a C-tripping characteristic, it delivers 10 kA breaking capacity per IEC 60947-2 at DC — enough to clear high-energy faults on 400–750 V DC bus systems common in industrial drives, UPS, and solar combiner panels. The C-curve (5–10× In) handles moderate inrush from contactor coils or DC power supplies without nuisance trips.
Width of 72 mm (4 modular units) and depth of 76 mm (70 mm installation depth behind the panel) — standard 35 mm DIN-rail footprint. Mounting position any, fastens via the quick-assembly system (snap-on). Thermal derating is published: 59.85 A at 40 °C, 58.21 A at 45 °C, 56.57 A at 50 °C, 54.81 A at 55 °C — relevant when populating adjacent breakers in a crowded enclosure. Halogen-free and silicon-free construction for clean-room or sensitive electronics areas.
