Product details

The Schneider Electric A9P64340 is a 40 A, D-curve, 3-pole miniature circuit breaker from the Acti9 iC40N series, rated for distribution applications. Its 10 kA Icu at 400 V AC (per EN/IEC 60947-2) gives it headroom for high-fault industrial panels, while the 6 kA Icn (per EN/IEC 60898-1) covers the residential/commercial coordination side. The D curve's magnetic trip threshold — 10 to 14 x In (EN/IEC 60898-1) or 12 x In ±20% (EN/IEC 60947-2) — is sized for motor and transformer inrush, not general lighting or resistive loads.

Clip-on mounting to DIN rail, 54 mm wide (6 x 9 mm pitches), with tunnel terminals accepting up to 16 mm² rigid or 10 mm² flexible. Tightening torque 2 N.m top or bottom. The IP20 finger-safe front suits enclosed distribution boards; the IP40 modular enclosure rating covers the body inside a panel. Padlocking device provision for lockout/tagout.
