The Schneider Electric A9D61845 is an Acti9 iC60N RCBO — a residual current breaker with overcurrent protection (RCBO) that combines a 45 A thermal-magnetic MCB and a 30 mA earth-leakage trip in a single 18 mm wide module.
Where it fits and how it mounts
Clip-on mounting onto standard DIN rail — the 18 mm width occupies two 9 mm pitches. The neutral is on the left, and the device is designed for outgoing (load-side) circuits. Screw-clamp terminals accept up to 25 mm² rigid on the top and 16 mm² on the bottom; torque the top connection to 3.5 N·m and the bottom to 2 N·m. IP20 body, IP40 in a modular enclosure — fine for a dry indoor panel, not for washdown areas.
The A9D61845 carries a current-production lifecycle status. It is part of the Acti9 iC60 family, a widely specified range across Asia-Pacific and European markets.
Certified to AS/NZS 61009.1, IEC 61009-1, and IEC 61009-2-2 — the RCBO-specific standards for residual current and overcurrent protection. The limitation class is 3, meaning it limits let-through energy under fault conditions.
