Breaking capacity and dual-standard certification
The Schneider Electric A9F07470 is an Acti9 iC60H miniature circuit breaker rated 0.5 A, 4-pole, with a C-curve magnetic trip at 8 x In ±20 %. Its headline figure is the 70 kA breaking capacity (Icu) at 220…240 V AC and 380…415 V AC per EN/IEC 60947-2, dropping to 50 kA at 440 V AC and 15 kA Icn at 400 V per EN/IEC 60898-1. That 70 kA rating means it clears high-fault currents typical of industrial distribution panels without upstream cascading — the SCCR headroom is real for a 0.5 A device.
Dual-certified to EN/IEC 60898-1 (household / commercial) and EN/IEC 60947-2 (industrial). The 60947-2 certification gives you Category A utilization (no intentional short-time delay) and pollution degree 3 — meaning it's rated for the conductive dust and humidity you'd see in a factory floor panel, not just a clean office board. Overvoltage category IV suits main-distribution-board installation. The C-curve (8 x In magnetic trip) is standard for moderate inrush loads — think small contactor coils, control transformers, or lighting banks. At 0.5 A, this is sized for a control-circuit feeder, not a motor branch.
Panel integration and lifecycle
Mounts on standard DIN rail (9 mm pitch, 8 modules wide). Terminals accept 1…25 mm² rigid or 1…16 mm² flexible on double terminals top and bottom — torque to 2 N·m. The white housing and trip-indicator flag give clear visual status.
