The Schneider Electric A9Z32491 is a 4-pole residual current circuit breaker (RCCB) from the Acti9 iID family, rated 100 A at 380-415 V AC, with a 100 mA earth-leakage sensitivity and Type A-SI (Super Immunised) protection. The 100 mA sensitivity means it trips on ground faults above that threshold but tolerates the higher leakage typical of drives, UPSs, and other power-electronics loads without nuisance tripping — a common pain point in mixed-load panels.
