The Schneider Electric C10R3MA013 is a ComPacT NSX100R three-pole moulded-case circuit breaker (MCCB) with a magnetic-only MA trip unit rated 12.5 A at 65 °C, built for motor protection in industrial power distribution. The MA trip unit provides magnetic-only short-circuit protection (I), meaning it responds to fault currents but not to overloads — the motor starter's overload relay handles thermal protection. This coordination keeps the breaker from tripping on motor inrush while still clearing a bolted fault.
Breaking capacity that keeps the line running
Rated 200 kA Icu at 415 V AC (50/60 Hz) per IEC 60947-2, this breaker can interrupt a 200 kA prospective fault current without damage — selectivity headroom for a high-fault point in the distribution, like a motor control centre fed by a large transformer. At 690 V AC the Icu drops to 45 kA; at 525 V AC it holds 65 kA.
Connection pitch 35 mm. IP40 enclosure protection, IK07 impact resistance.
