Frame size and fit
Frame Size R6 determines the physical mounting footprint, gland-plate layout, and bus-bar arrangement. If you're swapping into an existing R6 cabinet, the drill pattern and door cutout match the standard ABB R6 envelope. For a new panel, the R6 frame dictates the minimum enclosure depth and the bus-bar cross-section for the incoming supply.
