Product details

Overview

The C25F44B240 is a 4-pole ComPacT NSX molded case circuit breaker rated 240 A at 40 °C with an 85 kA interrupting capacity at 440 V AC, fitted with a MicroLogic 4.2 AB electronic trip unit for overload, short-time, instantaneous, and earth-leakage protection.

Compared to the 3-pole C25N3 (250 A, 690 V, distribution), the C25F44B240 adds a fourth pole, drops the current rating to 240 A, and is listed for special applications rather than general distribution — choose C25N3 when the BOM calls for 3-pole distribution duty at higher voltage.
