The Schneider Electric A9R71463 is a 4-pole Acti9 iID residual current circuit breaker (RCCB) rated for 63 A continuous load on a 380-415 V AC 50/60 Hz network.
Clip-on DIN rail mount, 8 x 9 mm pitch modules wide (72 mm). Neutral on the left, poles labelled for standard panel layout. Terminals accept 1-35 mm² rigid or 1-25 mm² flexible; strip 14 mm, torque to 3.5 N.m.
Current-production part in the Acti9 range.
63 A rated current (In) matches the main switch or upstream MCB rating for a 3-phase submain. 30 mA sensitivity is the standard for socket-outlet and general-purpose circuits in most IEC countries — catches body-contact faults without nuisance tripping on normal leakage from filters or VFDs. Voltage-independent tripping means the device breaks the circuit on a ground fault even if the phase voltage collapses — no auxiliary supply needed.
