It is designed specifically for motor protection — the MA curve provides short-circuit (magnetic) protection only, no thermal overload, relying on a separate motor starter or overload relay for the thermal element. This is standard practice for motor branch circuits where the MCCB clears faults and the overload relay handles running protection. Rated 100 kA Icu at 240 V AC and 70 kA at 415 V AC per IEC 60947-2, this breaker handles high available fault current common in industrial distribution — a 100 kA SCCR at the lower voltage means it can be applied on the secondary side of a large transformer without requiring a current-limiting fuse upstream. At 690 V AC the Icu drops to 10 kA, so verify the system voltage matches the rating. ## Integration notes Mounts on a backplate — no DIN rail. Front-connect terminals top and bottom, 35 mm pole pitch. IP40 enclosure rating (finger-safe), IK07 impact resistance. Pollution degree 3 environment (conductive pollution, typical in industrial panels). Overvoltage category III. Horizontal or vertical orientation allowed, flat on the back.","metaTitle":"Schneider C10H3MA003 ComPacT NSX 100H, 2.5 A MA Trip, 100 kA","metaDescription":"Schneider C10H3MA003 ComPacT NSX100H MCCB, 3-pole, 2.5 A magnetic-only trip unit, 100 kA Icu at 240 V AC.
