The Schneider Electric C60H4P3AC is a 4-pole miniature circuit breaker from the Multi9 C60 range, rated 3 A with a C-curve trip characteristic (5...10 x In magnetic tripping limit). It carries a 10 kA Icn breaking capacity at 230/400 V AC per EN 60898, and higher Icu ratings under IEC 60947-2 — up to 50 kA at 250 V DC for the 4P configuration. The thermal-magnetic trip unit protects distribution circuits in commercial and industrial panels.
Occupies 8 x 9 mm pitches (72 mm wide, 81 mm tall, 73 mm deep). The toggle handle provides local ON/OFF indication and a contact position indicator confirms isolation status per IEC 60947-2.
Breaking capacity and duty ratings
The C-curve (5...10 x In) suits mixed resistive and inductive loads where moderate inrush is expected — typical for distribution sub-circuits feeding contactor coils, small motors, or lighting banks. The 10 kA Icn at 230/400 V AC meets EN 60898 for domestic/commercial installations; the IEC 60947-2 Icu ratings extend to 15 kA at 400...415 V AC and 30 kA at 230...240 V AC. For DC applications, the 4P series connection yields 40 kA Icu at 125 V DC and 50 kA at 250 V DC. The Ics (service breaking capacity) is 7.5 kA at 230/400 V AC per EN 60898, meaning the breaker can be reclosed after clearing a fault at that level without replacement.
