It breaks fault currents up to 10 kA at 400 V AC, certified to both EN 60898 and IEC 60947-2 — meaning it covers residential/infrastructure panelboards and light commercial distribution where the utility-side fault level lands at 10 kA or below.
Panel fit and physicals
Mounting position is unrestricted, so you can lay it sideways in a shallow enclosure if the cable bend radius allows. The IP20 rating applies with conductors connected; keep the front cover sealed (it's sealable per spec) if the panel sees dust or casual contact.
Rated 400 V AC phase-to-phase, with a maximum operating voltage of 440 V AC for multi-phase circuits. The 10 kA breaking capacity holds at both standards — no derating needed between EN 60898 (household) and IEC 60947-2 (industrial) at this voltage. The 10 000 mechanical operating cycles typical is fine for a distribution board; if you're switching it daily as a disconnect, watch the cycle count.
