The MGPC4050 is a corner unit from the Schneider Electric PowerPacT 4 series, designed for 400/630/800 A panelboards. It measures 500 mm wide by 400 mm high in a cream RAL 9001 finish — a structural enclosure corner that mates with the panelboard chassis to complete the assembly.
What the dimensions mean for fit
The 500 mm width and 400 mm height are the envelope dimensions of the corner piece itself, not the panelboard it attaches to. When you spec this into a PowerPacT 4 assembly, the corner unit occupies the top or bottom corner of the panelboard frame — the 400/630/800 A rating of the panelboard determines the bus capacity, while the corner unit is the same physical shell across that range. If you are replacing a damaged corner or building a new lineup, verify that your existing panelboard is a PowerPacT 4 series; the corner bolt pattern and sealing interface are series-specific.
Panelboard destination and color
The MGPC4050 is explicitly listed for 400/630 A and 800 A panelboards — it covers the full PowerPacT 4 main-lug and main-breaker range in one corner SKU. The cream RAL 9001 finish matches the standard Schneider panelboard enclosure color for indoor installations. No special-order paint required for a matching lineup.
