Product details

Rated 40 A continuous at 220…240 V AC, 50/60 Hz, it is sized for outgoing submain or feeder protection in a distribution board.

Clip-on mount to DIN rail, 36 mm wide (4 x 9 mm pitches), 81 mm tall, 68 mm deep. Neutral on the left. Biconnect terminals accept 1…35 mm² rigid or 1…25 mm² flexible; strip 14 mm, torque to 3.5 N·m. IP20 body, IP40 inside a modular enclosure — standard for panelboard installation, not for wet-area standalone use.

The Acti9 ID K range is an established Schneider line, so BOM continuity is stable.
