Product details

The A9P64640 is a 40 A, D-curve miniature circuit breaker from the Acti9 iC40N line, 1P+N, rated 10 kA Icu at 230 V AC per EN/IEC 60947-2 and 6000 A Icn per EN/IEC 60898-1. The D curve's magnetic trip threshold of 10–14 × In tolerates high inrush currents.

Deployment context

Clip-on mounting to DIN rail (EN 60715) and a 36 mm footprint (2 × 18 mm pitches) mean it fits standard consumer units and sub-distribution boards. IP20 finger-safe terminals; the modular enclosure achieves IP40 when installed in a cabinet.
