The MGP0632L23 is a 2-pole PowerPacT 4 molded case circuit breaker from Schneider Electric, rated 63 A at 40 °C with a thermal-magnetic TM-D trip unit providing LI protection (overload and short-circuit). Breaking capacity is 25 kA Icu and 25 kA Ics at 415 V AC 50/60 Hz — the Ics equals Icu, meaning the breaker can be reclosed after a fault at full rated short-circuit without derating, a useful feature for service continuity in panel designs. Rated insulation voltage is 750 V, impulse withstand voltage 8 kV. The unit is panel-mounted, backplate-supported, and can be installed horizontally or vertically. Phase connection is L2-L3.
The breaker occupies a 2-module (35 mm per module) footprint on a backplate. Panel-mounting with horizontal or vertical orientation gives flexibility in crowded enclosures. The toggle control is manual; no earth-leakage protection is integrated — external RCD required if needed. Mechanical durability is rated at 20,000 cycles; electrical durability is 20,000 cycles at rated current (277 V In/2) and 10,000 cycles at full 277 V In. These figures are typical for a distribution-grade MCCB and support moderate switching duty in panel feeder applications.
