Product details

The C63W35E630 is a Schneider Electric ComPacT NSX630HB2 molded-case circuit breaker, 3-pole, rated 630 A at 40 °C, with a MicroLogic 5.3 E electronic trip unit.

Trip unit and protection

The MicroLogic 5.3 E provides L (long-time overload), S (short-time short-circuit), and I (instantaneous short-circuit) protection, plus integrated energy metering and power-quality data via the LCD display.

Mounting and environment

Mounts on a backplate in horizontal or vertical orientation, flat against the panel. Front connections on both line and load sides simplify bus-bar or cable routing in a distribution panel. Derate above 2000 m altitude if the installation is at elevation.
