The Schneider Electric A9D54232 is an Acti9 iC60 RCBO — a combined miniature circuit breaker and residual-current device in a single 36 mm wide, 2-pole module that clips onto DIN rail.
Rated 32 A (In) with a breaking capacity of 10 kA Icn at 220–240 V AC per EN/IEC 61009-2-1, and 15 kA Icu per EN/IEC 60947-2. The 10 kA Icn is the service breaking capacity — the current level the device can interrupt repeatedly under standard conditions — while the 15 kA Icu is the ultimate (one-shot) capacity. The 300 mA earth-leakage sensitivity suits circuits where a 30 mA device would cause nuisance tripping — typically fixed equipment without hand-held loads, such as distribution sub-mains, lighting circuits, or industrial socket outlets where the protective conductor path is monitored but not personnel-protection critical. If your application requires direct touch protection, a 30 mA RCBO variant is the correct choice.
Tunnel-type terminals accept 1–35 mm² rigid or 1–25 mm² flexible conductors; wire-strip length is 12 mm for top or bottom connection. The toggle provides local signalling for ON, OFF, and fault-trip positions. IP40 in a distribution enclosure, IP20 at the terminals.
Carries quality labels KEMA-KEUR, IMQ, VDE, and NF, covering acceptance in key European markets. Overvoltage category III per IEC 60364, suitable for fixed-installation distribution boards. Tropicalisation class 2 for humid environments up to 95 % RH at 55 °C.
