Applications
The Wiegmann universal cutout is used in
large freestand and floorstand enclosures.
Operator Adapter Kits are required in order
to install the various manufacturers’ hard-
ware. Note that 400 A (or greater) discon-
nect switches and 600 A (or greater) circuit
breakers need to use the “Large” or “High
Amp” cutout, which is provided in the
WA21ABVA kit for Allen-Bradley variable-
depth disconnect switches or the WA21ITE
kit for Siemens (and select other manufac-
turers) flex-cable devices. The “Large” or
“High Amp” cutout accepts the larger oper-
ating handle whose mounting hole centers
are 6.500-in. apart.

• The mechanical interlock is activated by
the master door which prevents the slave
doors from being opened first. Doors can
be closed in any order
• Disconnects come with a universal cutout
which provides mounting for most dis-
connect operators by using operator
adapters
• FTC rolled lip around all sides of enclo-
sure opening excludes liquids and conta-
minants
Finish
• ANSI 61 gray polyester powder inside
and out over phosphatized surfaces
• Included back panels are white polyester
powder over phosphatized surfaces
Accessori es
• See pages J1-J22
• Blank adapter plates on pages F61
IMPORTANT
• Disconnect switch or circuit breakers,
operating handle and operating mecha-
nism are not furnished with enclosure
and must be ordered separately from the
disconnect manufacturer
• Operator adapter plates are required with
this enclosure and must be purchased
separately. See pages F61 to select the
proper operator adapter for the brand
and type of disconnect being used
• Disconnect ordering information is lo-
cated on page F39
• Review space occupied by disconnect
drawings on page F38 and disconnect
tables on pages F51-F60 to determine if
the disconnect device you are using will
fit the enclosure size you have selected
