Hammond 1447SN4K12 48x37.38x12 In Type 4 Steel Disconnect Enclosure

The 1447SN4K12 is a Type 4 mild steel wallmount disconnect enclosure from the 1447S N4 series, with a continuous hinge door secured by clamps and a multi-vendor flange cutout. It measures 48 x 37.38 x 12 in (1219 x 949 x 305 mm) and is intended for electricians, panel builders and OEM engineers housing a flange-mounted disconnect switch or circuit breaker operating mechanism.

It is formed from 14 gauge steel with continuously welded seams and welded brackets for wall mounting. A formed lip on the door and enclosure excludes flowing liquids and contaminants, a seamless poured-in-place gasket seals the door, and the door is secured with stainless steel clamps. The continuous hinge uses a stainless steel pin that can be pulled to remove the door, and a cover interlock bracket is welded to the door.

The K12 size is 48 x 37.38 x 12 in with a 45.00 x 33.00 in inner panel and a listed shipping weight of 200 lbs (90.72 kg). The drawing shows a door opening of 33.22 x 45.20 in and about 12.07 in of usable depth.

Collar studs carry the included removable 12 gauge inner panel, a bonding stud is provided on the door with a grounding stud in the enclosure, and a literature pocket sits on the inside of the door. Cutouts suit flange-mounted variable depth mechanisms from ABB Controls, Allen Bradley (1494V/1494U), C-H Westinghouse (C361/C371), General Electric (Type STDA), Siemens I-T-E (Max-Flex) and Square D (Class 9422); Square D bracket-mounted, 9422TG1 and TG2 devices are not accepted. Disconnects and operating mechanisms are ordered separately.

The series is listed to UL 508A and CSA Type 3R and 4 and complies with NEMA Type 3R, 4 and 12 and IEC 60529 IP66, with appropriate components required to maintain these ratings. This part carries UL File E65324 and CSA certificate LR21001 and is REACH and RoHS compliant.
