Product details

Overview

The C25W45E250 is a 4-pole ComPacT NSX molded case circuit breaker rated 250 A with a 100 kA ultimate breaking capacity at 690 V AC, fitted with a MicroLogic 5.2 E electronic trip unit and an LCD display for energy metering and event logs. It is in active production and ships as a fixed-mount unit with toggle control, Class II front face, and a 35 mm terminal pitch for panel integration.

Against the 4-pole C40F4, the C25W45E250 carries a higher 100 kA IC versus 85 kA but a lower 250 A continuous rating versus 400 A — pick the C25W45E250 when the fault duty exceeds 85 kA and the load stays under 250 A.
