Product details

It is designed specifically for motor protection — the MA trip responds only to short-circuit (magnetic) faults, not overloads, so the motor's own overload relay handles thermal protection. The 2.5 A rating at 65 °C means the trip unit is calibrated for that current at elevated ambient temperature — important when the breaker is inside a warm enclosure. The magnetic-only characteristic (no thermal bimetal) makes this unsuitable for cable or general distribution protection; it belongs on a motor branch circuit where a separate overload relay provides the thermal element.

Front connection both top and bottom; connection pitch is 35 mm.

Overvoltage category III, utilisation category A. IP40 finger protection, IK07 impact resistance. The manufacturer provides the usual compliance documentation (declaration of conformity, test certificates) on request for FAT/SAT packages.

Frequently asked questions

What is C10F3MA003 used for?

It is a motor-protection circuit breaker with a magnetic-only (MA) trip unit, rated 2.5 A. It provides short-circuit protection on motor branch circuits where a separate overload relay handles thermal protection.

What is the breaking capacity of C10F3MA003 at 415 V?

36 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which is the rating that governs most European industrial installations.

Where can I buy C10F3MA003?

It is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance documentation is available for C10F3MA003?

The breaker carries EN/IEC 60947-2 certification, UL 60947-4-1 listing for the breaking capacity ratings, and is suitable for isolation per the standard. Declaration of conformity and test certificates are available on request.
