Product details

The C25W35E250 is a Schneider Electric ComPacT NSX250HB2 molded-case circuit breaker, 3-pole, rated 250 A at 40 °C with a MicroLogic 5.2 E electronic trip unit. The trip unit provides L (long-time overload), S (short-time short-circuit), and I (instantaneous) protection, plus energy metering and communication of time-stamped event tables and power-quality data.

The MicroLogic 5.2 E is an electronic trip unit with adjustable curves, so you can coordinate selectivity with downstream devices without swapping trip units. The 20-minute thermal memory before and after tripping means the breaker 'remembers' prior heating — useful for repeated overloads on a conveyor or pump start.

Integration notes

Front connection for both line and load sides simplifies bus-bar or cable routing. The toggle control and LCD display give local status without opening the panel door. IP40 and IK07 mean it's protected against tools and small wires but not washdown — keep it inside the enclosure.
