The Schneider Electric A9N19755 is an Acti9 DPN Vigi residual-current circuit breaker with overcurrent protection (RCBO), combining a 13 A thermal-magnetic trip (B curve) and 30 mA earth-leakage protection in a single 36 mm wide, 1P+N module.
The 13 A rated current (In) with B-curve magnetic trip (3–5 × In) means this RCBO is sized for residential or light commercial lighting and socket circuits where inrush is moderate — a B curve clears fast on short-circuit but avoids nuisance trips on small motor or capacitive loads. The 30 mA earth-leakage sensitivity provides personnel protection against direct contact, meeting the standard for socket-outlet circuits in most IEC 60364 installations. Breaking capacity is 6000 A Icn at 220–240 V AC, 50/60 Hz, which covers the typical prospective short-circuit current at the distribution board in most residential and small commercial panels.
Tunnel terminals accept 0.75–16 mm² rigid or 0.33–10 mm² flexible conductors, with a stripping length of 15 mm and tightening torque of 2 N·m. IP20 rated on the body, IP40 in a modular enclosure — suitable for dry indoor distribution boards.
