The Schneider Electric C63F42D630 is a ComPacT NSX630F moulded-case circuit breaker rated 630 A at 40 °C, with a MicroLogic 2.3 electronic trip unit providing overload (L), short-time short-circuit (So), and instantaneous (I) protection per EN/IEC 60947-2. The 4-pole (4P) configuration with neutral on the left suits distribution panels where full phase-plus-neutral isolation is required.
The MicroLogic 2.3 electronic trip unit lets you adjust the long-time pickup and delay, short-time pickup and delay, and instantaneous threshold — not a fixed thermal-magnetic, so you can fine-tune coordination with downstream devices. If your available fault current exceeds that, step to the 'H' or 'L' version in the same frame.
Front connections top and bottom, 45 mm pole pitch — standard for panel busbar systems. Overall footprint 255 mm high × 185 mm wide × 110 mm deep. Six accessory slots accept shunt trips, auxiliary contacts, motor mechanisms, or communication modules without increasing the breaker width.
