Panel-fit and breaking capacity
The A9F05206 is a 2-pole, 6 A miniature circuit breaker from the Acti9 iC60N family, designed for DIN-rail mounting in distribution panels. Its 36 mm width (4 x 9 mm pitches) fits standard modular enclosures; the 78.5 mm depth and 91 mm height leave clearance for gland plates and cable ducts. Rated Icu at 220…240 V AC is 20 kA; at 380…415 V AC it holds 10 kA. Icn per EN/IEC 60898-1 is 6 kA at 400 V AC. For a 6 A device these margins cover most industrial distribution boards without cascading upstream. The D curve magnetic trip operates at 12 x In ±20 %, so it tolerates the inrush of small motors, transformers, or solenoid banks without nuisance tripping on start-up.
Dual-standard certification and lifecycle
Certified to both EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (household / similar) — a dual rating that lets the same part serve control-panel distribution and branch-circuit protection under one BOM line. Lifecycle status is current production. Pollution degree 3 per IEC 60947-2 suits environments with conductive pollution or occasional condensation — typical for factory-floor panels not sealed to NEMA 4X.
Connection and wiring
The thermal-magnetic trip unit requires no external power — the breaker is self-powered for overcurrent sensing. IP20 finger-safe terminals are standard for enclosed distribution boards. A separate earth-leakage block (Vigi iC60) can be added on the downstream side for RCD protection without replacing the MCB.
