Product details

The Schneider Electric A9N2P40DIN is an Acti9 xC60 miniature circuit breaker rated at 40 A with a D curve, 2 poles, and a breaking capacity of 10 kA at 380–415 V AC (IS/IEC 60947-2).

Height 85 mm, depth 77.5 mm — fits standard distribution board cutouts. Biconnect bottom terminals allow daisy-chaining without additional busbars. IP20 finger-safe protection for panel-internal use.

Frequently asked questions

What is the breaking capacity of the A9N2P40DIN?

10 kA Icn at 380–415 V AC 50/60 Hz per IS/IEC 60947-2, and 6 kA Icu at 100–125 V DC per the same standard.

What does the D curve mean on this breaker?

The D curve sets the magnetic trip threshold at 12 x In ±20%, so the breaker tolerates high inrush currents typical of motor loads, transformers, or welding equipment without nuisance tripping.

Where can I buy the A9N2P40DIN?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.
