Rated 25 A continuous with 30 mA earth-leakage sensitivity, Type A, it handles 400 V AC three-phase-plus-neutral circuits and is listed as current-production. This is the part you'd spec into a group-incomer position on a DIN-rail sub-distribution board where you need combined overcurrent and earth-leakage protection in one compact footprint.
Type A means it detects pulsating DC residual currents, which covers modern single-phase electronics (switched-mode supplies, variable-speed drives) that a plain AC-only RCD would miss. Voltage-independent trip means the RCD doesn't need the line voltage to operate; it stores enough energy from the fault itself to open the contacts, so it still protects even if the neutral is lost upstream. Rated 25 A on a 400 V AC network at 50/60 Hz — this is a 3P+N device, so it switches all three phases and the neutral. The insulation voltage is 440 V, and impulse withstand is 4 kV per EN/IEC 61009-2-1, which is the product standard for combined RCBOs. That's typical for a panel-protection device; not designed for frequent switching duty like a contactor, but fine for the occasional manual trip-test and fault clearing it will see in service.
Clip-on DIN-rail mount, 6 pitches at 9 mm. Depth 74 mm, height 99.5 mm. Neutral left. Tunnel terminals: 1 to 16 mm² rigid, 1 to 10 mm² flexible. Torque 2 N·m, strip 14 mm. IP20/IP40.
Current-production part in Schneider's Acti9 range.
