The Schneider Electric C25N47E250 is a ComPacT NSX250N molded-case circuit breaker with a MicroLogic 7.2 E electronic trip unit, rated 250 A at 40 °C.
The MicroLogic 7.2 E provides L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and R (earth-leakage) protection — all adjustable. The electronic trip unit logs time-stamped events, energy metering, and demand values, readable from the LCD display.
The C25N47E250's Icu varies by system voltage: 90 kA at 240 V AC, 50 kA at 380/415 V and 440 V, 36 kA at 500 V, 35 kA at 525 V, and 10 kA at 660/690 V AC. Under UL 60947-4-1 it's rated 85 kA at 240 V, 50 kA at 480 V, and 15 kA at 600 V AC. That's a wide coverage for mixed-voltage plants — a single breaker can serve a 480 V distribution board or a 600 V motor control center, but the 10 kA at 690 V means it's not a 690 V main.
Mounts on a backplate, flat on the back, in horizontal or vertical orientation. Five accessory slots for shunt trips, aux contacts, or communication modules.
