Product details

The A9K23640 is a Schneider Electric Acti9 iK60N miniature circuit-breaker (MCB) rated 40 A at 30 °C, curve B, 1P+N, with a 6 kA breaking capacity at 230 V AC (EN/IEC 60898-1). The B curve (magnetic trip 3–5× In) means it handles moderate inrush — typical for resistive and general lighting loads, not motor starts with high locked-rotor current.

Width 36 mm (4 × 9 mm pitches), depth 78.5 mm, height 85 mm. Clip-on mounting on DIN rail, neutral on the left. Single terminal top and bottom accepts 1–35 mm² rigid; tightening torque 3.5 N·m. Strip length 14 mm. IP20 enclosure — suitable for dry indoor panels, not washdown areas.

Ratings and compliance

Suitability for isolation per EN/IEC 60898-1. Electrical durability 10,000 cycles, mechanical 20,000 cycles. Limitation class 3.
