RCCB for group incomer duty, 63 A, 30 mA, Type AC
The Schneider Electric A9KR13463 is a 4-pole residual current circuit breaker (RCCB) from the Acti9 ID K range, rated 63 A with 30 mA earth-leakage sensitivity. It is designed for group incomer positions in AC networks at 380-415 V, 50 Hz, and provides Type AC earth-leakage protection — suitable for sinusoidal AC fault currents from appliances, lighting, and resistive loads. Rated breaking and making capacity is Idm 630 A / Im 630 A, and the device is voltage-independent — the trip mechanism does not rely on the mains voltage to operate, so it clears a residual fault even if the phase voltage collapses. This is a key reliability feature for group incomer duty where a line-to-earth fault could otherwise starve the trip coil. Compliance is documented to EN/IEC 61008-1 and SS 97:part 1, with a SAFETY Mark quality label. Pollution degree 2, tropicalisation class 2 per IEC 60068-1, and IP20 (IP40 in modular enclosure) per IEC 60529. The 8/20 µs impulse withstand rating of 200 A confirms compatibility with standard surge environments without nuisance tripping.
Terminals accept Biconnect top or bottom: 1-35 mm² rigid or 1-25 mm² flexible, with a wire stripping length of 14 mm and tightening torque of 3.5 N.m.
