Product details

The A9F04340 is a 40 A, 3-pole miniature circuit breaker from the Schneider Acti9 iC60N series, rated for distribution circuits. The 36 kA Icu at 12...133 V AC and 10 kA Icu at 380...415 V AC (per EN/IEC 60947-2) give substantial fault-clearing headroom for industrial panel feeders; the 6 kA Icn at 400 V (per EN/IEC 60898-1) is the domestic/commercial rating. Thermal-magnetic trip technology with a separate earth-leakage block (add-on) means the MCB itself provides overcurrent and short-circuit protection; add the Vigi module for ground-fault protection.

Snaps onto standard DIN rail (mounting support: DIN rail). Width is 54 mm (6 x 9 mm pitches), height 91 mm, depth 78.5 mm — occupies three modular spaces for the 3P unit. Double terminals top and bottom accept 1...35 mm² rigid or 1...25 mm² flexible; torque to 3.5 N.m. Strip length 14 mm. IP20 finger-safe terminals; no washdown rating, so keep inside a panel enclosure.
