The C25W36E100 is a ComPacT NSX 3-pole circuit breaker carrying a MicroLogic 6.2 E electronic trip unit rated 100 A at 40 °C. The electronic trip unit provides L (long-time overload), S (short-time short-circuit), I (instantaneous), and G (ground-fault) protection, all adjustable via the LCD display. The 20-minute thermal memory before and after tripping prevents nuisance reclosing on a hot conductor — the breaker remembers the thermal state of the protected circuit even after a trip, so it won't re-energize until the conductor has cooled. Mounts on a backplate; IP40 and IK07 ratings suit panel-mount indoor use where occasional tool impact or dust ingress is possible.
Five accessory slots accept communication modules, auxiliary contacts, or shunt trips. The LCD display shows instantaneous and demand values, power quality, protection settings, time-stamped event logs, and energy metering — useful for commissioning verification without a separate meter.
