Product details

The Schneider C10H3MA003 is a ComPacT NSX100H molded-case circuit breaker, 3-pole, fitted with a magnetic-only (MA) trip unit rated 2.5 A at 65 °C. 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.

Frequently asked questions

Where can I buy C10H3MA003 and how do I get a price?

The C10H3MA003 is sourced and quoted to order against an RFQ through independent distribution channels. Submit an RFQ for current availability and pricing — confirmed at quote time, not listed here.

What is C10H3MA003's listed range on this component line?

The range is ComPacT, the product name is ComPacT NSX, and the device short name is NSX100H. This is the H-frame (70 kA at 415 V AC) version of the NSX platform.

What compliance documentation does this brand provide for C10H3MA003?

The C10H3MA003 is certified to EN/IEC 60947-2. It carries a suitability-for-isolation marking per that standard. The IP40 and IK07 ratings are tested per IEC 60529 and IEC 62262 respectively. Pollution degree 3 per IEC 60664-1. The evidence does not list RoHS or REACH declarations, but as a current-production Schneider catalog item, those compliance documents are typically available on request.
