The 3UHD7211918N4SS is a three-door, 72.13 in high freestanding disconnect enclosure that stretches to 118.25 in wide at 18.13 in deep (1,832 x 3,004 x 461 mm). Made from Type 4X 304 stainless steel, it suits long control lineups where ceiling height or sight lines call for a 72 in cabinet.
The body is formed from 12 gauge 304 stainless steel with smooth, continuously welded seams and a natural brushed finish. A flange trough collar around each door opening helps exclude liquids and contaminants, oil resistant gaskets are permanently secured, and the three doors hang on heavy duty lift-off hinges. Heavy duty lifting eyes are anchored into reinforced top corners for placement.
It carries two inner panels, 60.00 x 33.75 in (1524 x 857 mm) and 60.00 x 72.00 in (1524 x 1829 mm). Per the drawing, each of the three door openings is 35.82 in wide by 61.91 in high, with 17.41 in of usable depth. The panels are formed 10 gauge steel on collar studs with panel supports, and a removable center post eases panel installation.
The enclosure has a pre-installed multi-vendor flange cutout for disconnect operators, with interlock hardware included. The right-hand door is the main door, and its handle has a screw defeater and padlock hasp; the secondary handle has a padlock hasp. A mechanical interlock stops the auxiliary door opening first, and a three point latch with roller ends closes each door. Disconnect switches, circuit breakers and operators are ordered separately; verify operator compatibility in advance.
The enclosure is listed to UL 508A and CSA Type 3R, 12, 4 and 4X (UL File E65324, CSA Cert. LR21001), complies with NEMA Type 3R, 12, 13, 4, 4X and IEC 60529 IP66 when appropriate components are used, and is REACH and RoHS compliant. It ships on a skid at 1530 lbs (694.00 kg).
