The Schneider Electric A9R52263 is a 2-pole residual current circuit breaker (RCCB) from the Acti9 iID series, rated 63 A with 30 mA earth-leakage sensitivity, Type AC, for 230-240 V AC 50/60 Hz networks. The 30 mA sensitivity covers basic shock protection for general-purpose circuits; Rated breaking capacity is 1500 A (Idm and Im), sufficient for fault clearing on most sub-distribution boards where the upstream overcurrent device limits prospective fault current below that level.
Clip-on mounting on 36 mm wide DIN rail, occupying 4 x 9 mm pitches. Neutral on the left, toggle control, padlocking provision for lockout/tagout. Terminals accept 1-35 mm² rigid or 1-25 mm² flexible conductors; tighten to 3.5 N·m. Wire strip length 14 mm. IP20 finger-safe, IP40 inside a modular enclosure.
