Schneider Electric C10H3MA100 ComPacT NSX100H 3P 100 A 70 kA MA Fixed Moulded Case Circuit Breaker

The Schneider Electric C10H3MA100 is a 3P, 100 A ComPacT NSX100H moulded case circuit breaker built for motor protection, fitted with an MA magnetic-only trip unit delivering 70 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 H frame sits at the top tier of the ComPacT NSX100 breaking-capacity ladder (70 kA at 380/415 V AC), above the N (50 kA) and F (36 kA) frames of the same ComPacT NSX100 footprint. Because the MA trip unit has no thermal (overload) element, this C10H3MA100 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 100 A rating to match the motor's locked-rotor current.
