The Schneider Electric MGN19756 is a 2-pole Acti9 DCP Vigi RCBO — a combined residual-current circuit breaker with overcurrent protection, rated 25 A with a 30 mA earth-leakage sensitivity. It integrates both overcurrent (thermal-magnetic) and ground-fault protection into a single 36 mm wide DIN-rail module, saving panel space compared to a separate MCB + RCCD pair. This RCBO is designed for 50 Hz AC networks only, with a toggle control for ON/OFF/reset and local signalling showing ON, OFF, and fault-trip status. The 30 mA earth-leakage sensitivity provides personal protection against direct contact — the standard threshold for socket-outlet circuits in most IEC-based wiring regulations.
Height 85 mm, depth 76 mm. Tunnel terminals accept 1–35 mm² rigid or 1–25 mm² flexible cable; strip 12 mm, torque 2 N·m. Not padlockable, so if lockout/tagout is required for your panel, plan for a separate isolation means upstream or a lockable switch-disconnector. The contact-position indicator gives visual confirmation of the state without needing to test voltage.
