Product details

The Schneider Electric A9K24203 is a 2-pole miniature circuit breaker from the Acti9 iK60N series, rated 3 A with a C-curve trip characteristic and a 6 kA breaking capacity at 400 V AC. It's a thermal-magnetic device built to EN/IEC 60898-1 for distribution in residential or light commercial panels. The 36 mm width (4 x 9 mm pitches) clips onto standard DIN rail, so it slots into any existing Acti9 or Multi9 board without extra adapters.

The C-curve (5–10 x In magnetic trip) means it holds through mild inrush from LED drivers or small transformers but trips fast on a hard short.

Clip-on DIN rail mount, 36 mm wide — occupies two pole positions in a standard distribution board. Tunnel terminals accept 1–25 mm² rigid or 1–16 mm² flexible; strip 14 mm and torque to 2 N·m.

Frequently asked questions

Where can I buy A9K24203 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is A9K24203's listed depth (78.5 mm) on this component line?

The depth is 78.5 mm, which is standard for the Acti9 iK60N 2-pole form factor and fits most DIN-rail enclosures without depth clearance issues.

What compliance documentation does this brand provide for A9K24203?

The breaker is certified to EN/IEC 60898-1, carries an IP20 rating per IEC 60529, and is rated for isolation per the same standard. Schneider Electric typically provides CE declaration and RoHS/REACH compliance data on request for this series.
