Product details

Overview

The C125N32AFM is a Schneider ComPacT NS new generation 3-pole molded case circuit breaker rated 1250 A with a MicroLogic 2.0 A electronic trip unit providing L (long-time overload) and I (instantaneous short-circuit) protection. It breaks 85 kA at 690 V AC and meets EN/IEC 60947-2.

The C125N32AFM carries 3 poles; the C125N42AFM carries 4 poles with neutral protection settings (No protection (3D), 0.5 x Ir (3D + N/2), 1 x Ir (4D)). The C125N42AFM also adds short-time protection (S) and adjustable Isd and Tsd. If your panel is wired for 4-wire distribution, the C125N42AFM is the correct choice; the C125N32AFM fits 3-pole-only feeds.
