Overview
The C25B47E100 is a 4-pole ComPacT NSX molded case circuit breaker rated 100 A with a 40 kA Icu breaking capacity at 440 V AC, fitted with a MicroLogic 7.2 E electronic trip unit that provides L, S, I, and earth-leakage protection. The trip unit includes an LCD display for time-stamped event logs, power quality data, and energy metering, and the breaker ships as a fixed-mount unit with a toggle control handle.
How it compares
Compared to the 3-pole C25N3 (250 A, 85 kA at 690 V), the C25B47E100 offers 4 poles for three-phase-plus-neutral distribution, a lower 100 A rating, and a 40 kA Icu at 440 V — pick the C25N3 when the BOM requires 3 poles and a higher interrupting rating at 690 V.
