The Schneider Electric A9D67325 is an Acti9 iC60 RCBO — a combined 3-pole residual-current circuit breaker with overcurrent protection, rated 25 A with a C-curve trip characteristic and 30 mA earth-leakage sensitivity. The thermal-magnetic trip unit handles the overcurrent side; the integrated earth-leakage block covers the 30 mA residual current. Breaking capacity is 6 kA Icn / Icu at 380–415 V AC 50 Hz, compliant with EN/IEC 60947-2 and EN/IEC 61009-2-1, so it's sized for standard commercial and light industrial panelboards where fault levels stay under that threshold.
At 25 A rated current and 3 protected poles, it covers a 3-phase load up to roughly 17 kVA at 400 V. The limitation class 1 rating (per EN/IEC 61009-2-1) means it lets through a higher let-through energy than a current-limiting breaker; that's normal for this class and acceptable when the upstream device is coordinated.
Mounts via clip-on to DIN rail (EN 60715). The 3-pole body takes 6 × 9 mm pitches on the rail — 54 mm wide. Tunnel terminals on top and bottom accept 1–35 mm² rigid or 1–25 mm² flexible; strip length is 12 mm. The 9 mm pole pitch matches standard busbar systems for the Acti9 range. Local signalling shows ON, OFF, and fault-trip status on the toggle. IP40 in a distribution enclosure, IP20 on the terminals.
