The MGP0632L31 is a Schneider Electric PowerPacT 4 molded case circuit breaker (MCCB) — 2-pole, 63 A at 40 °C, rated 415 V AC 50/60 Hz.
Above that temperature, thermal derating applies — a panel running at 50 °C will need a higher-rated frame or forced ventilation. The 8 kV impulse withstand voltage (Uimp) covers typical transient overvoltages in a 400 V class installation.
Integration Notes
Panel-mounted via backplate — not a DIN-rail snap-on, so plan for screw-fixed mounting in the enclosure. Accepts horizontal or vertical orientation, which helps in tight gland-plate layouts. The toggle control is manual; no motor operator or shunt trip is included, so remote tripping requires an external accessory. 2-module width (35 mm per module) on the backplate footprint.
