It's rated 15 kA breaking capacity per EN 60898-1 and 25 kA per IEC 60947-2, so in a panel you get the higher fault-interrupt rating for industrial coordination studies while still meeting the residential/commercial standard. The B curve means it trips at 3–5× rated current — good for resistive or lighting loads where you don't want nuisance trips from motor inrush.
Mounts in any position — no derating needed for horizontal or upside-down orientation. Combined terminal top and bottom means you can feed from either direction without swapping the breaker.
Certified to IEC/EN 60898-1 and IEC/EN 60947-2 for the 15/25 kA ratings respectively, plus UL 1077 and CSA C22.2 No. 235 for the 5 kA North American supplementary protector rating. Energy limitation class 3 — fast enough for most downstream coordination needs. Supply frequency 50/60 Hz, operating voltage 400 V AC single-phase or 440 V multi-phase.
