Schneider NSYPMM Steel Mounting Plates
There is an option on the double door enclosures of using a single
mounting plate which is the width of the cabinet minus 125mm or 2
separate mounting plates. The only 2 exceptions to this rule is that
a PMM55 and PMM75 must be selected for the PLA5123/PLA5124 as there is
not a single mounting plates for these cabinets.
