The Schneider Electric A9Q12225 is an Acti9 Vigi iC60 add-on residual current device — a 2P, 25 A, AC-type unit with 100 mA sensitivity and instantaneous trip. Rated for 230...415 V AC at 50/60 Hz, it carries EN/IEC 61009-1 and 61009-2-1 compliance, with an impulse withstand of 250 A (8/20 µs) and a rated insulation voltage of 500 V AC.
The 100 mA sensitivity is a common specification for socket-outlet circuits in commercial installations where 30 mA would cause nuisance tripping on leakage from connected equipment. The voltage-independent trip technology means the device clears a fault even if the line voltage is lost — a reliability advantage over electronically dependent RCDs. The IP20 rating covers the terminal area; the modular enclosure achieves IP40 inside the panel.
