The MA trip unit responds to fault currents only; motor overload protection is handled separately by a thermal relay or motor protection relay in the circuit. ## Breaking capacity and isolation Rated breaking capacity reaches 85 kA Icu at 500 V AC 50/60 Hz, 80 kA Icu at 525 V AC, and 75 kA Icu at 660/690 V AC — the HB1 breaking capacity code. Mounts on a backplate — flat on the back, horizontal or vertical orientation accepted. The front connection (upside and downside) uses a 35 mm connection pitch. IP40 enclosure protection keeps out tools and particles >1 mm; IK07 impact resistance handles a 2 J drop. Operating altitude derating begins above 2000 m. No earth-leakage protection built in (no Vigi module). Relative humidity range 0–95 %. The toggle control is manual; no auxiliary contacts or shunt trip are included in this base variant.","metaTitle":"C10V3MA050 ComPacT NSX circuit breaker, 50 A, 85 kA Icu, mag","metaDescription":"Schneider Electric C10V3MA050 ComPacT NSX 3P circuit breaker, 50 A magnetic-only MA trip unit, 85 kA Icu at 500 V AC.

The key difference among ComPacT NSX variants is the trip unit type: MA (magnetic-only for motor protection) versus TM (thermal-magnetic for general distribution). If the application requires thermal overload protection, a TM trip unit variant would be the alternative, but it would change the protection characteristic."},{"question":"What compliance documentation does the brand provide for C10V3MA050?","answer":"The breaker is certified to EN/IEC 60947-2 and carries suitability for isolation marking per that standard.
