Schneider Electric C16F3MA150 ComPacT NSX160F 3P 150 A 36 kA MA Fixed Moulded Case Circuit Breaker

The C16F3MA150 is a 3-pole Schneider Electric ComPacT NSX160F moulded case circuit breaker with a 150 A magnetic-only MA trip unit and 36 kA breaking capacity (Icu) at 380/415 V AC. Rated operational voltage (Ue) is 690 V AC. Built for motor protection, it provides instantaneous short-circuit tripping only, leaving thermal overload protection to a separate device.

Selection Notes

Because the MA trip unit on the C16F3MA150 has no thermal element, it is meant to pair with a downstream thermal overload relay or motor-protection controller that handles the overload side — using it alone on a feeder leaves that circuit with short-circuit protection but no running overload protection. The 9...14 x In adjustable instantaneous pickup lets the trip threshold be set above the motor's starting inrush. For a self-contained motor circuit with built-in thermal protection, the TM-D variants in this same NSX160F frame are the simpler choice.
