Product details

The Schneider Electric C10F3MA050 is a ComPacT NSX100F 3-pole MCCB with a magnetic (MA) trip unit rated 50 A at 65 °C. It is designed for motor protection — the MA trip unit provides only magnetic short-circuit protection (no thermal overload), so it pairs with an external overload relay for a complete motor branch circuit. Breaking capacity is 85 kA Icu at 240 V AC (UL 60947-4-1), 36 kA at 415 V AC, and 22 kA at 525 V AC per IEC 60947-2. Mounts on a backplate; front connection top and bottom. IP40, IK07. Pollution degree 3.

Motor protection branch

The MA trip unit is magnetic-only — it reacts to short-circuit current only. For a motor branch, pair this MCCB with a separate thermal overload relay (e.g., TeSys LR series) to provide overload protection. The 50 A rating at 65 °C matches a typical 22 kW motor on 400 V three-phase. Electrical durability: 50,000 cycles at 440 V In/2; 30,000 at 440 V In. Mechanical durability: 50,000 cycles.
