The Schneider Electric A9Z02263 is a 2-pole residual current circuit breaker (RCCB) from the Acti9 ID K range, rated 63 A with 30 mA earth-leakage sensitivity, Type A. Rated operational voltage is 220–240 V AC at 50/60 Hz, with an insulation voltage of 440 V AC and impulse withstand of 4 kV. The 30 mA sensitivity covers personnel protection (indirect contact) per EN/IEC 61008-1, and the Type A classification means it detects pulsating DC residual currents — relevant for circuits feeding electronics or rectified loads.
Mounting and connection details
Width is 36 mm (4 x 9 mm pitches). Terminals accept 1–35 mm² rigid or 1–25 mm² flexible cable, with a stripping length of 14 mm and tightening torque of 3.5 N·m. Biconnect terminals allow looping in/out without separate links.
IP20 on the body, IP40 in a modular enclosure per IEC 60529. Operating temperature range -5 to 40 °C, storage -30 to 70 °C. Pollution degree 2. Certified to EN/IEC 61008-1 and EN/IEC 61008-2-1, with VDE quality label. The device is voltage-independent for the residual current trip — no auxiliary supply needed for earth-fault detection.
