Overview
The C25N47E160 is a Schneider ComPacT NSX molded case circuit breaker rated 160 A at 40 °C with a 90 kA breaking capacity at 440 V AC, built on a 4-pole frame. It carries a MicroLogic 7.2 E electronic trip unit offering L, S, I, and R protection curves, plus an LCD display for energy metering and event logs.
How it compares
The C25N47E160 uses a 4-pole frame and breaks 90 kA at 440 V AC, whereas the C25N3 is a 3-pole unit rated 85 kA at 690 V AC with a 250 A switching current — pick the C25N47E160 when the BOM requires four poles and the 160 A rating, or the C25N3 for three-pole 250 A distribution at higher voltage.
