What the frame size tells you
Frame R11 is a physical envelope that governs mounting footprint, gland-plate space, and bus-bar layout. If you are replacing an existing drive or fitting into a panel with pre-drilled mounting holes, verify that the R11 dimensions match the cutout and that the cable entry zones align with your gland plate.
