Product details

The Schneider Electric A9N19757 is an Acti9 DPN Vigi RCBO — a single-module residual-current circuit breaker with overcurrent protection, rated 20 A with a 6 kA breaking capacity at 230 V AC and curve B tripping characteristic. Integrated earth-leakage protection eliminates the need for a separate RCCB, saving one DIN-rail position in the distribution board.

The 20 A rated current (In) and curve B magnetic trip (3–5 x In) mean this RCBO clears short-circuit faults quickly on resistive and lighting circuits where inrush is low — typical for final subcircuits in commercial and residential distribution boards.

Tunnel terminals accept 0.75–16 mm² rigid or 0.33–10 mm² flexible conductors; strip length 15 mm, tighten to 2 N.m. The 9 mm connection pitch between phase and neutral matches the Acti9 busbar system for daisy-chaining outgoing circuits.

Frequently asked questions

What is the breaking capacity of A9N19757?
