Product details

The A9Z25291 is a Schneider Electric Acti9 iID residual current circuit breaker (RCCB) — a voltage-independent, 2-pole device rated at 100 A with 300 mA earth-leakage sensitivity, Type A selective (time-delayed) for AC networks at 220…240 V, 50/60 Hz.

100 A rated current (In) handles the full incoming feed. 300 mA sensitivity with Type A selective characteristic discriminates against transient leakage and trips on sustained earth faults above 300 mA. Rated conditional short-circuit current is 10 kA. Impulse withstand is 3000 A at 8/20 µs waveform. Rated insulation voltage (Ui) is 500 V AC, and impulse withstand voltage (Uimp) is 6 kV.

Neutral is on the left — verify busbar orientation before assembly.
