Rated at 125 A (In) with a 30 mA earth-leakage sensitivity, this RCD sits on the high-current end of the Acti9 Vigi C120 range. The 30 mA trip threshold is the standard for personnel protection against direct-contact faults — it catches leakage currents that would be dangerous through the chest path, while avoiding nuisance tripping from normal cable capacitance on a clean installation.
Standards and installation conditions
