The C25F47E250 is a Schneider Electric ComPacT NSX250F molded case circuit breaker, 4-pole, rated 250 A at 40 °C with a MicroLogic 7.2 E electronic trip unit. At 415 V AC the breaking capacity is 36 kA Icu, still enough for most distribution boards in European industrial plants. The trip unit covers L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and R (earth-leakage) protection — one device handles both overcurrent and ground-fault, so no separate RCD needed downstream. The LCD display on the front gives you real-time metering and alarm readouts without opening the door.
Mounting and integration — checklist for the panel builder
