Integrator note: A9F08270 Acti9 iC60H
The Schneider Electric A9F08270 is a 2-pole miniature circuit breaker from the Acti9 iC60H series, rated 0.5 A with a D tripping curve. The D curve (magnetic tripping limit 12 x In +/- 20 %) means this breaker tolerates high inrush currents — typical for motor, transformer, or lighting ballast loads — without nuisance tripping. At 0.5 A, it protects a small motor or control transformer circuit where the start-up surge exceeds the C-curve threshold. Breaking capacity is 70 kA Icu at 415 V AC per EN/IEC 60947-2, and 15 kA Icn at 400 V AC per EN/IEC 60898-1.
The A9F08270 carries a current lifecycle status from the manufacturer. For audit and tender purposes, the part is listed as suitable for isolation per both standards, and includes a contact position indicator and trip indicator for visual confirmation of status.
The DIN-rail mount and 36 mm width (4 modules) fit standard distribution board layouts. Double terminals top and bottom accept 1…25 mm² rigid or 1…16 mm² flexible conductors; strip length 14 mm, tightening torque 2 N.m. IP20 finger-safe protection is maintained when installed in an enclosed panel. Earth-leakage protection requires a separate block (not integrated), so plan for an external RCCB or RCBO if ground-fault protection is needed on the same circuit.
