The breaking capacity is 6 kA per EN 60898 and 15 kA per IEC 60947-2, so it handles fault currents up to 15 kA in industrial panels where the higher standard applies.
The 16 A rating at 30 °C derates with ambient temperature: 15.2 A at 40 °C, 14.4 A at 50 °C, and 12.8 A at 70 °C. The B-curve avoids nuisance tripping on inrush from small transformers. At 18 mm wide (1 modular width), it fits a standard DIN-rail enclosure slot. Depth is 77 mm, installation depth 70 mm — check your enclosure depth before committing; some shallow consumer units won't clear the 77 mm.
Integration notes
Mounts in any position on DIN rail. The 1 MW width leaves room for adjacent breakers or accessories in a multi-pole assembly.
