The MGN19772 is a Schneider Electric Acti9 DCP Vigi residual current breaker with overcurrent protection (RCBO) — a single device combining a 10 A thermal-magnetic MCB (C-curve) with a 30 mA earth-leakage module, all in a 3-pole, clip-on DIN-rail package. It's built to EN/IEC 61009-2-1 and EN/IEC 60947-2, with a 10 kA breaking capacity at 220–240 V AC, 50 Hz. That 30 mA sensitivity means it protects against lethal shock in final circuits — standard for socket outlets and wet-area subcircuits where the code demands both overcurrent and residual-current protection in one unit.
Rated 10 A continuous, 10 kA breaking capacity under EN/IEC 60947-2; the Icn rating under EN/IEC 61009-2-1 is 6000 A. The 30 mA earth-leakage threshold is the standard for personal protection in most residential and commercial final circuits. Thermal-magnetic trip technology gives you the bimetal overload curve plus a solenoid for short-circuit — no electronics to fail. The RCBO format saves a module width compared to a separate MCB + RCCB pair: 6 × 9 mm pitches (54 mm wide). Clip it onto a DIN rail (mounting support: DIN rail per). Wire stripping length: 12 mm. IP20 on the body, IP40 inside a modular enclosure — fine for dry indoor panels. Tropicalisation class 2 means it handles 95 % RH at 55 °C without derating. Local signalling shows ON, OFF, and fault trip via a toggle and a contact position indicator. Non-padlockable, so if your site requires lockout, plan for an external lockable isolator upstream.
