The 30 mA threshold covers personnel protection (indirect contact) per IEC 61008, while the 100 A rating handles the full load current of a distribution outgoer. Clips onto DIN rail, neutral on the left, and the toggle gives a clear visual contact-position indicator. The 380-415 V AC 50/60 Hz operational voltage covers standard three-phase European and many Asian distribution voltages. The 6 kV impulse withstand and pollution degree 3 qualify it for industrial panels where transient overvoltages and conductive dust are present. The 30 mA sensitivity means it will trip on leakage currents above that threshold — fast enough for personnel protection but not so sensitive that nuisance tripping from normal cable capacitance becomes a problem on a properly wired circuit. The voltage-independent tripping technology means it doesn't need a separate power supply to detect leakage; it uses the fault current itself, so it works even if the neutral is lost upstream. The 72 mm width occupies 8 modules of 9 mm pitch on the DIN rail. The 73.5 mm depth and 91 mm height are standard for the Acti9 range, so it fits alongside MCBs and other modular devices in a distribution board. Terminals accept 1-35 mm² rigid or 1-25 mm² flexible; strip 14 mm and torque to 3.5 N·m. IP20 body, IP40 within a modular enclosure — fine for indoor panel use. The padlocking option allows lockout/tagout for safe isolation during maintenance.","metaTitle":"Schneider Electric A9R11491S Acti9 iID RCCB, 100 A, 30 mA, 4","metaDescription":"Schneider Electric A9R11491S Acti9 iID RCCB. 100 A rated current, 30 mA sensitivity, 4P, Type AC.
