- Description
The C25N32D250 is a 3-pole Schneider Electric ComPacT NSX250N moulded case circuit breaker rated 250 A, with an electronic MicroLogic 2.2 trip unit and 50 kA breaking capacity (Icu) at 380/415 V AC. Rated operational voltage (Ue) is 690 V AC. The MicroLogic 2.2 adds adjustable long-time and short-time protection on top of the fixed instantaneous stage.

Selection Notes
The C25N32D250's 100...250 A long-time adjustment lets the breaker be set below its 250 A frame rating to match the feeder cable, and the 1.5...10 x Ir short-time delay gives it the selective-coordination stage that the TM-D breakers in this NSX250 range lack. Where that short-time stage is not needed, the TM-D 250 A variant in the H-rated 70 kA frame covers the same current with simpler, non-electronic protection and higher Icu.
