Product details

It won't nuisance-trip on the startup surge that would pop a B-curve breaker on the same circuit. Rated insulation voltage 500 V AC, overvoltage category IV, pollution degree 3 — this breaker is rated for the dirty, surge-prone environment you find in main distribution boards and industrial switchgear, not just clean sub-panels. The thermal-magnetic trip unit covers both overload (thermal bimetal, slow response) and short-circuit (magnetic coil, instantaneous).

Snaps onto a DIN rail (mounting support: DIN rail per the spec). The 72 mm width (8 x 9 mm pitches) means it takes four module spaces on the rail — plan your enclosure fill factor accordingly. Double terminals top and bottom accept 1-25 mm² rigid or 1-16 mm² flexible. Tighten to 2 N.m. Strip 14 mm. The double-terminal design lets you daisy-chain the feed through without extra connectors — a time-saver when wiring a multi-pole distribution board. IP20 finger-safe terminals. No washdown rating — keep it inside the panel, not on the machine frame.

Certified to both EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (domestic/similar) — it carries dual standards, so it's accepted in industrial control panels and building distribution boards alike. Suitability for isolation is confirmed under both standards.

Frequently asked questions

How do I get current pricing and availability for A9F08403?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is A9F08403's breaking capacity?

70 kA Icu at 400 V AC per EN/IEC 60947-2, and 15 kA Icn at 400 V AC per EN/IEC 60898-1.

What is the closest alternative to A9F08403 in the Acti9 family?

The iC60N (device short name iC60N) is the standard-capacity sibling with a lower breaking capacity — typically 10-25 kA versus the 70 kA of this iC60H. Choose the H variant when the prospective short-circuit current at the installation point exceeds the N variant's rating.
