Product details

The Schneider Electric A9F03140 is a 1-pole miniature circuit-breaker from the Acti9 iC60N family, rated 40 A with a B-curve trip characteristic.

Breaking capacity — the real fault-handling envelope

Rated 6 kA Icn at 230 V AC per EN/IEC 60898-1, and 10 kA Icu at 220–240 V AC per EN/IEC 60947-2. At 12–60 V AC the Icu jumps to 36 kA — relevant for control transformer secondaries or low-voltage distribution. The dual standard (EN/IEC 60898-1 for domestic MCB and EN/IEC 60947-2 for industrial circuit-breaker) means this part qualifies for either application class. Use the 60898-1 rating for residential boards, the 60947-2 rating for industrial panel schedules where the higher Icu is needed.

Snaps onto standard 35 mm DIN rail (EN 60715) and occupies 2 x 9 mm pitches (18 mm total width), so it fits one modular position in a distribution board. Depth is 78.5 mm, height 91 mm — allow clearance for the toggle and wiring. IP20 finger-safe protection on the front, but the terminals are live when the breaker is on — standard for enclosed distribution boards.

For a BOM freeze or critical-spare holding, this is a stable, widely stocked order code with no imminent replacement risk.

Frequently asked questions

Where can I buy A9F03140 and how do I get a price?

The A9F03140 is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, not estimated here.

What is A9F03140's listed depth (78.5 mm) on this component line?

The depth is 78.5 mm, with a height of 91 mm and width of 18 mm (2 x 9 mm pitches). It mounts on standard 35 mm DIN rail.

What compliance documentation does this brand provide for A9F03140 (RoHS, REACH, UL, IEC)?

The A9F03140 is certified to EN/IEC 60947-2 and EN/IEC 60898-1. It carries IP20 protection per IEC 60529 and tropicalisation class 2 per IEC 60068-1. For RoHS/REACH declarations and any UL listing, request the manufacturer's compliance pack at quote time — the evidence does not list those marks directly.
