Product details

The A9F05304 is a Schneider Electric Acti9 iC60N miniature circuit breaker rated 4 A with a D tripping curve, 3 poles, and a 50 kA breaking capacity at 400 V AC.

At 440 V AC the Icu drops to 25 kA, and under the 60898-1 standard the Icn is 10 kA at 400 V AC. That 10 kA Icn is the figure for domestic/commercial final circuits; the 50 kA Icu is what matters for industrial coordination studies.

Snaps onto standard DIN rail (mounting support: DIN rail). The 3-pole body occupies 6 x 9 mm pitches (54 mm wide), so it fills three module spaces in a distribution board.

Frequently asked questions

Where can I buy the A9F05304 and get a price?

The A9F05304 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the D curve on the A9F05304 used for?

The D curve has a magnetic tripping threshold of 12 x In ±20%, designed for loads with high inrush current such as small motors, transformers, and discharge lighting where a B or C curve would cause nuisance tripping on startup.

What compliance documentation does the A9F05304 carry?

The A9F05304 is dual-certified to EN/IEC 60947-2 and EN/IEC 60898-1, and carries IP20 finger-safe protection (IEC 60529). It is suitable for isolation per both standards. Tropicalisation class 2 per IEC 60068-1 is also listed.
