Product details

The A9F05120 is a 1-pole Acti9 iC60N miniature circuit breaker rated 20 A with a D tripping curve. Breaking capacity is rated per two standards: 36 kA Icu at 12-60 V AC and 10 kA Icu at 220-240 V AC under EN/IEC 60947-2, plus 6 kA Icn at 230 V under EN/IEC 60898-1. The dual rating means this breaker qualifies for industrial panel SCCR calculations (60947-2) and for residential or commercial final-distribution boards (60898-1) — one part covers both compliance paths. Thermal-magnetic trip unit, category A (no intentional short-time delay), so it coordinates as a downstream device in a selective system. Rated insulation voltage 500 V AC, overvoltage category IV — suitable for main incoming panels, not just sub-distribution.

Double terminals top and bottom accept 1-25 mm² rigid or 1-16 mm² flexible — enough for a 20 A feed with parallel outgoing circuits. Tightening torque 2 N.m; strip length 14 mm. IP20 finger-safe terminals, white housing, toggle control with trip-indicator flag. Pollution degree 3, tropicalisation class 2 per IEC 60068-1 — rated for humid, non-condensing panel environments up to 95 % RH at 55 °C.

Frequently asked questions

What is the closest pin-compatible alternative to A9F05120 in this component family?

Within the Acti9 iC60N family, the closest alternative would be a different current rating or curve code in the same 1P form factor (18 mm width, DIN rail mount, same terminal specs). No single pin-compatible substitute is listed as an official successor; the iC60N platform shares the same physical footprint across all ratings, so a 16 A or 25 A D-curve unit would swap in the same panel position if the load allows.

What is A9F05120's listed depth (78.5 mm) on this component line?

The A9F05120 has a depth of 78.5 mm, width of 18 mm, and height of 91 mm — standard iC60N dimensions that fit all common distribution board enclosures with DIN-rail mounting.

What compliance documentation does this brand provide for A9F05120 (RoHS, REACH, UL, IEC)?

The A9F05120 is certified to EN/IEC 60947-2 and EN/IEC 60898-1. It carries suitability for isolation per both standards, pollution degree 3, overvoltage category IV, and tropicalisation class 2 per IEC 60068-1. For RoHS/REACH declarations and UL listing status, refer to the Schneider Electric product compliance portal using the order code A9F05120.
