The height and width are showing below for frame WX-A up to 2500A. The panel cutout
size is same for all types of W Nmaster2, which makes it easy to arrange them in
switchboards. Panel cutout for front remains same.

The sheet steel structure of WiNmaster 2 is extremely compact, considerably reducing

overall dimensions.

W Nmaster 2 circuit breakers comes in two frame sizes.
