The Schneider Electric MGP0631L2 is a PowerPacT 4 series molded case circuit breaker (MCCB) — one pole, rated 63 A at 40 °C, for 230 V AC 50/60 Hz distribution circuits. It uses a thermal-magnetic TM-D trip unit with LI protection (thermal overload and magnetic short-circuit), so the bimetal handles the overload curve and the solenoid trips instantly on fault current. The 25 kA Icu/Ics at 230 V AC gives you symmetrical breaking capacity — service and ultimate ratings match at 25 kA, which simplifies coordination studies.
Panel-mounted via backplate, with horizontal or vertical orientation allowed. Toggle control for manual on/off and trip reset.
Rated insulation voltage (Ui) is 750 V, impulse withstand (Uimp) is 8 kV — that covers standard 230/400 V distribution with margin for surge events. Electrical durability: 20,000 cycles at rated current and 277 V, halving to 10,000 cycles at 2x In. Mechanical durability matches at 20,000 cycles.
Designed and tested to BS EN 60947-2, the harmonized standard for low-voltage switchgear and controlgear — covers the breaking capacity, isolation function, and endurance. Utilisation category A (non-selectively coordinated for most distribution applications).
