Overview
The C25R35E250 is a Schneider ComPacT NSX molded case circuit breaker rated 250 A at 40 °C with a 200 kA ICu breaking capacity at 690 V AC, three-pole, fixed-mount, carrying a MicroLogic 5.2 E electronic trip unit for LSI protection. It is in active production and ships with an LCD display, Class II front face, and 20-minute thermal memory before and after tripping.
Selection and sizing
The 200 kA ICu at 690 V AC makes this breaker suitable for high-fault distribution panels where SCCR headroom is critical; the 250 A continuous rating and LSI curve (long-time, short-time, instantaneous) cover feeder and main breaker duty in industrial switchboards.
