PreFerred-Cutout overview
aPPliCation
Enclosures having the preferred cutout are sized for use with up to
200A disconnect switches and up to 400A circuit breakers unless
otherwisespecied.Thepreferredcutoutacceptsthesmaller
operating handle whose mounting hole centers are 4.688 in. apart.
Preferred cutouts are standard in mild steel wall-mount enclosures,
modular enclosures and some select large mild steel enclosures.
They are also present on all standard stainless steel offerings. 400
A (or greater) disconnect switches and 600 A (or greater) circuit
breakersrequirethe“Large”or“HighAmp”cutout.Thiscutout
accepts the larger operating handle whose mounting hole centers
are 6.500-in. apart. This large cutout is only available on PROLINE-
DD Disconnect Packages and Type 1 Free-Stand Enclosures.
Operator adapter for preferred cutouts must be ordered separately
tobeusedwithA21S,A28S4,A4SandWS2Denclosures.Preferred
cutouts are designed to house the following:
