Schneider Electric C16H3MA150 ComPacT NSX160H 3P 150 A 70 kA MA Fixed Moulded Case Circuit Breaker

The C16H3MA150 is a 3-pole Schneider Electric ComPacT NSX160H moulded case circuit breaker with a 150 A magnetic-only MA trip unit and 70 kA breaking capacity (Icu) at 380/415 V AC. Rated operational voltage (Ue) is 690 V AC. The H performance level gives it roughly double the Icu of the equivalent F-rated NSX160F frame for motor circuits with higher fault current.

Selection Notes

Choosing the H-rated C16H3MA150 over the F-rated NSX160F MA150 makes sense once the board's prospective fault current exceeds 36 kA — at 70 kA Icu this frame has roughly double the headroom. As an MA trip unit it provides instantaneous short-circuit protection only, so it needs a separate thermal overload relay downstream for complete motor protection; the TM-D variants in this same NSX160H frame bundle thermal and magnetic protection together for circuits that do not need that separation.
