The Schneider Electric C60H3P10AC is a C60H-series miniature circuit breaker from the Multi9 range, rated 10 A at 30 °C with a C trip curve (magnetic tripping between 5 and 10 times In). Three poles, thermal-magnetic trip unit, rated for distribution duty in a 35 mm symmetrical DIN-rail panel. Breaking capacity hits 30 kA Icu at 230...240 V AC and 10 kA Icu at 440 V AC, both per IEC 60947-2 — enough headroom for most commercial and light industrial sub-distribution boards.
The C curve means the magnetic trip fires between 5 and 10 times the 10 A rating (50–100 A instantaneous). That suits mixed resistive-inductive loads — lighting, small motor circuits, general-purpose socket outlets — where you need a short delay to ride through inrush without nuisance tripping. Three protected poles on a 3P device; the neutral is switched if you add the separate earth-leakage block. That's generous for a 10 A breaker — you can land larger feed conductors without adapter lugs.
Snaps onto 35 mm symmetrical DIN rail. Width is 54 mm (6 x 9 mm pitches), depth 73 mm, height 81 mm. Toggle actuator with ON/OFF indication and a contact position indicator for visual confirmation of the mechanical state.
