Schneider Electric C10N3MA025 ComPacT NSX100N 3P 25 A 50 kA MA Fixed Moulded Case Circuit Breaker

The Schneider Electric C10N3MA025 is a 3P, 25 A ComPacT NSX100N moulded case circuit breaker built for motor protection, fitted with an MA magnetic-only trip unit delivering 50 kA breaking capacity at 380/415 V AC. Short-circuit pickup is adjustable from 6...14x In, and the device carries a 690 V rated operational voltage on a fixed backplate mount.

Selection Notes

The N frame sits at the mid tier of the ComPacT NSX100 breaking-capacity ladder (50 kA at 380/415 V AC), between the F (36 kA) and H (70 kA) frames of the same ComPacT NSX100 footprint. Because the MA trip unit has no thermal (overload) element, this C10N3MA025 variant is selected purely to match a motor's starting current at the magnetic pickup — adjustable 6...14x In — while overload protection is handled by a separate thermal relay or contactor-integrated device downstream; pick a sibling with a higher or lower 25 A rating to match the motor's locked-rotor current.
