It occupies 4 modular width units (72 mm) on a DIN rail and carries a 10 kA breaking capacity per both EN 60898 and IEC 60947-2 — meaning it can safely interrupt a fault current up to 10,000 A without welding its contacts or cascading the fault upstream.
Sealable terminals (padlockable) for lockout/tagout compliance.
Breaking capacity: 10 kA at 400 V AC per EN 60898 (the household-and-similar standard) and the same 10 kA per IEC 60947-2 (the industrial standard). That's a single rating that satisfies both compliance frameworks — no split between domestic and industrial SCCR values. Operating voltage max is 440 V AC multi-phase, so it covers 400/415 V three-phase networks with headroom. The 50/60 Hz rating covers both line frequencies globally. Power loss per pole is 1.4 W at rated current in hot state — 5.6 W total for the 4-pole assembly at full load, relevant for thermal budgeting in a sealed enclosure.
