The 2UHD907924N4SS pairs the full 90.13 in height with the deepest 24.13 in body in the two-door UHD SS range, for an overall size of 90.13 x 79 x 24.13 in (2,289 x 2,007 x 613 mm). It is aimed at builders of large disconnect and motor control assemblies that need both vertical panel space and depth in a Type 4X stainless 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 two doors hang on heavy duty lift-off hinges. Heavy duty lifting eyes are anchored into reinforced top corners for placement.
The drawing gives 23.30 in of usable depth, and the single inner panel is 78.00 in (1981 mm) high by 72.00 in (1829 mm) wide. 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 1384 lbs (627.77 kg).
