Product details

The Schneider Electric A9N18383 is an Acti9 C120N miniature circuit breaker rated 80 A at 30 °C with a D tripping curve (magnetic trip 10–14 x In). It's a 2-pole (2P) device for AC networks, breaking 10 kA Icn at 400 V AC per EN/IEC 60898-1 and 6 kA Icu at 440 V AC per EN/IEC 60947-2.

The tunnel terminals accept 1–50 mm² rigid or 1.5–35 mm² flexible, stripped 15 mm, torqued to 3.5 N·m. IP20 finger-safe front, pollution degree 3, overvoltage category IV — standard for main distribution panels. Neutral on the left, toggle control with ON/OFF indication.

The Acti9 C120 range is Schneider's heavy-duty residential and light-commercial MCB platform, and this 80 A D-curve variant is a standard catalogue item.

Frequently asked questions

What is the closest pin-compatible alternative to A9N18383 in this component family?

Within the Acti9 C120N family, the closest sibling is a different current rating or pole count — same footprint, same DIN-rail clip, same terminal layout. The D-curve and 2-pole configuration are what define the fit for high-inrush two-phase loads.

What compliance documentation does this brand provide for A9N18383?

The breaker is certified to EN/IEC 60947-2 and EN/IEC 60898-1, with IP20 protection per IEC 60529 and tropicalisation class 2 per IEC 60068-1. Standard Schneider documentation includes the declaration of performance and CE declaration of conformity.
