Product details

The Schneider Electric C25B44V100 is a ComPacT NSX moulded-case circuit breaker rated 100 A at 40 °C, 4-pole, with a MicroLogic 4.2 electronic trip unit and integrated earth-leakage protection. Its 40 kA Icu at 220/240 V AC (25 kA at 415 V) per IEC 60947-2 means it can safely interrupt fault currents up to that level on a 240 V distribution board without needing an upstream current-limiting fuse — a common spec for main or feeder breakers in commercial and light industrial panels.

The 20-minute thermal memory before and after tripping means the breaker remembers prior heating events, so repeated overloads close together trip faster — important for motor or transformer circuits that see inrush.

IP40 enclosure protection means it is suited for clean indoor panels — not washdown or outdoor use. The 35 mm connection pitch and front-facing terminals simplify busbar and cable routing in a distribution board. IK07 impact resistance handles incidental tool contact during panel assembly.
