Disconnect Enclosures

NEMA-rated disconnect enclosures, from Hubbell/Wiegmann, range in size from 20 X 21 X 8 in., wall-mountable to 84 X 197 X 18-in. heavy-duty free-standing units.

NEMA-12-rated SDN 12 Se ries single-door wall-mount disconnect enclosures, consist of 14-gauge steel bodies and doors with plasma-welded seams. Poured-in-place polyurethane seamless gaskets provide watertight and dustproof seals.

Designed to house Allen-Bradley 1494F flange-mounted disconnect switches and Bulletin 1949D flange-mounted operators for circuit breakers, the NEMA-12-rated ABN12 Series single-door wallmount flange-disconnect enclosure has predrilled holes in the bodies and door for mounting disconnect switches, operating mechanisms, and door hardware.

Series SSN4X NEMA-4X singledoor wall-mount enclosures are made of 14-gauge 304 stainlesssteel bodies and doors with continuously welded seams. Stainless steel door clamps feature closedcell neoprene and poured-in-place polyurethane gaskets for a watertight seal.

The WAX and WACPX heavy-duty NEMA-12 floor-mount disconnects enclosures, in "Right Flange" and "Center Post" models, are made from 10-gauge steel and feature mechanical interlocks to prevent the slave door from opening before the master door.

The heavy-duty NEMA-12 freestanding WAXM Series, made from 10-gauge steel, has mechanical interlocks so slave doors can only be opened after the master door (the doors can be closed in any order). These freestanding enclosures have body stiffeners for added rigidity and the center post is removable for easy panel installation.
