The C25F44V100 is a 4-pole ComPacT NSX250F molded case circuit breaker rated 100 A at 40 °C, fitted with a MicroLogic 4.2 electronic trip unit that provides L (long-time), So (short-time with fixed delay), I (instantaneous), and R (earth-leakage) protection in a single device. Its breaking capacity hits 85 kA Icu at 240 V AC (EN/IEC 60947-2) and 36 kA Icu at 415 V AC, which gives solid selectivity headroom for distribution panels feeding downstream subfeeds or motor control centers.
