The Hammond HCT483011H is a UL 508A Type 3R current transformer cabinet measuring 48 in high, 30 in wide and 11 in deep (1219 x 762 x 279 mm). It is designed as a current transformer box to house and protect instrument current transformers in outdoor applications, and it also serves as a general purpose enclosure for junction, meter, transformer and relay work. For electricians and panel builders, it provides protection against rain, sleet, snow and dripping water.

Because this cabinet is 30 in or wider, the body and covers are formed from 12 gauge galvanized steel. The top has an integral drip shield and the sides are seam free. Cover and enclosure are phosphatized and finished inside and out with a recoatable ANSI 61 smooth gray polyester powder.

The single removable door hangs on permanently installed lift-off hinges and closes with a hasp/screw closure that includes padlocking provisions. Per the part drawing, the door measures 30.24 in wide by 47.52 in high and the door opening is 27.94 in wide by 46.54 in high. Mounting holes run through the back of the enclosure on 27.00 in by 45.00 in centres, and ground studs are shown on both the body and the door.

Mounting studs are provided for an optional inner panel; the matching panel for this size is part number 18P4527. The cabinet complies with NEMA Type 3R and IEC 60529 IP24, and is listed as REACH and RoHS compliant. HCT483011H ships packaged in a box at a shipping weight of 110 lbs (49.90 kg).
