The Schneider Electric Acti9 iID A9Z81463 is a 4-pole residual current circuit breaker (RCCB) rated 63 A with 30 mA earth-leakage sensitivity, Type A protection.
63 A rated current (In) covers the main feeder or large submain in a distribution board — sized for loads like a multi-circuit lighting panel or a small motor control centre. Breaking and making capacity is rated Idm 1500 A / Im 1500 A — this is the RCCB's own fault-clearing capability under residual-current fault conditions, not the through-fault rating. The voltage-independent tripping technology means the RCCB will trip on residual current even if the line voltage is lost — important for safety when the supply is interrupted but a ground fault persists.
