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.","metaTitle":"A9F08403 Acti9 iC60H MCB, 4P D-curve 3 A, 70 kA","metaDescription":"Schneider Electric A9F08403 Acti9 iC60H miniature circuit breaker, 4-pole, D-curve, 3 A rated current, 70 kA breaking capacity.
