Product details

The A9F05340 is a 40 A, 3-pole miniature circuit breaker from Schneider Electric's Acti9 iC60N series, with a D tripping curve (12 x In magnetic trip, ±20 %). The 36 kA Icu at 12…133 V AC (EN/IEC 60947-2) is the maximum fault current it can safely interrupt at that voltage; at 220…240 V it's 20 kA, and at 380…415 V it's 10 kA. For distribution boards on a 400 V three-phase supply, the 10 kA Icu at 380…415 V and the 6 kA Icn at 400 V (EN/IEC 60898-1) are the numbers that govern the installation's prospective short-circuit current rating.

Snaps onto DIN rail (mounting support: DIN rail). Occupies 6 x 9 mm pitches (54 mm wide) — standard 3-pole width. Height 91 mm, depth 78.5 mm. IP20 finger-safe terminals. Double terminals accept 1…35 mm² rigid or 1…25 mm² flexible on top or bottom; strip length 14 mm, torque 3.5 N·m.

Suitability for isolation per both standards. Overvoltage category IV. Contact position indicator and trip indicator provide local visual status. Earth-leakage protection requires a separate block (not integrated).
