Product details

Overview

The C25B47E250 is a Schneider ComPacT NSX 4-pole molded case circuit breaker rated 250 A with a 40 kA breaking capacity at 440 V AC, fitted with a MicroLogic 7.2 E electronic trip unit. The trip unit provides LSI+R protection: overload (L), short-time short-circuit (S), instantaneous (I), and earth-leakage (R), making it suited for distribution panels requiring ground-fault detection.

Compared to the 3-pole C25N3 (85 kA at 690 V, basic frame), the C25B47E250 adds a fourth pole and earth-leakage protection but at a lower 40 kA Icu at 440 V. Choose the C25N3 when the BOM specifies a 3-pole basic frame with higher interrupting capacity; pick the C25B47E250 when a 4-pole earth-leakage MCCB is required.
