The MGN19762 is a 2-pole RCBO (residual current breaker with overcurrent protection) from the Acti9 DCP Vigi range, rated 10 A with a 30 mA earth-leakage sensitivity and a B tripping curve (3–5 × In magnetic release). That 30 mA sensitivity is the standard for personal protection against indirect contact in final circuits — it covers the same ground as a standalone RCCB but integrated into one module. The thermal-magnetic trip technology is the conventional dual-element type — bimetal strip for overload, solenoid for short-circuit. Clip-on mounting onto a DIN rail (35 mm per EN 60715) at 4 module pitches (36 mm per pole width) means it occupies 72 mm of rail space.
The 8/20 µs impulse withstand of 250 A confirms electromagnetic compatibility per that same standard. Tropicalisation class 2 indicates the part is treated for humidity and mould resistance in warm climates. The contact-position indicator (ON/OFF/fault trip) and suitability for isolation (EN 60947-2) mean it can serve as a local disconnection point when locked off — though it is not padlockable, so a separate lockout device would be needed for LOTO procedures.
