The Schneider Electric C60H4P10AC is a 4-pole miniature circuit breaker (MCB) from the Multi9 C60H range, rated 10 A with a C-curve trip characteristic (5–10 × In magnetic trip).
Under IEC 60947-2 the Icu climbs to 15 kA at 400–415 V AC and 30 kA at 230–240 V AC — the higher industrial rating matters when the MCB sits in a panel with a larger upstream transformer. DC ratings hit 25 kA at 125 V (2-pole series) and 50 kA at 250 V (4-pole series), so this 4P unit can break DC faults at those levels. The Ics (service breaking capacity) is 7.5 kA at 230/400 V AC per EN 60898 — that's the figure for repeated fault clearing without replacing the breaker.
Ambient operating range -25 to 60 °C, storage -40 to 70 °C; tropicalisation class 2 per IEC 60068-1 handles 95 % RH at 55 °C.
