The A9N19777 is a 1P+N RCBO from the Acti9 DPN Vigi family — a combined overcurrent and earth-leakage device in a single 36 mm wide module. Integrated earth-leakage protection means this single unit replaces both a MCB and a separate RCCB — saving a DIN-rail slot and reducing wiring. Clip-on mounting onto standard DIN rail, tunnel terminals accepting up to 16 mm² rigid, and a white modular enclosure rated IP20 (IP40 inside the panel) make it a straightforward swap-in for a failed or undersized RCBO on an outgoer.
