The 3-pole breaker is rated for 50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, and carries a 90 kA Icu at 220/240 V AC. The MA trip unit is set at 2.5 A at 65 °C, meaning it will trip magnetically on short-circuit currents above that threshold, but does not track thermal heating in the motor circuit. ## Motor protection — why the MA trip unit matters This breaker is built for motor protection duty (Category A, per IEC 60947-2). The magnetic-only trip unit (MA) is standard for motor branch circuits where a separate overload relay handles thermal protection. The 2.5 A rating at 65 °C means it's sized for a small motor load — roughly 1.1 kW at 400 V three-phase, depending on motor full-load amps. The 3D protected poles configuration covers all three phases. IP40 enclosure protection (finger-safe), IK07 impact resistance.","metaTitle":"Schneider Electric C10N3MA003 ComPacT NSX Circuit Breaker, 2","metaDescription":"Schneider Electric C10N3MA003 ComPacT NSX circuit breaker, 3-pole, 2.5 A magnetic trip unit, 50 kA breaking capacity at 415 V AC.
