Hammond DTT6401B460LG 400/460V Top-Mount Air Conditioner, 7160 BTU/h

The DTT6401B460LG is a 400/460 V top-mount enclosure air conditioner rated 7160 BTU/h (2100 Watts) at +95/+95F (+35/+35C), the largest capacity in the DTT 4000-7000 BTU/H indoor series. It is designed for OEM equipment builders and plant electricians cooling heavily loaded NEMA 12 control enclosures on higher-voltage supplies, especially where there is no room to mount a unit on the enclosure side.

Electrical ratings: 400/460 V (+/- 10%) at 50/60 Hz, power consumption 1300/1598 W, running current 3.35 / 3.3 A and starting current 10.1 / 12 A. The connection is a terminal block with plug. A hot gas bypass valve prevents evaporator freeze up while minimizing heavy inrush currents, and a door contact provision powers the unit down when the enclosure door is opened. The part description lists it as AIR CONDIT 7100BTU 460V LG.

Closed loop cooling keeps clean enclosure air recirculating without mixing with contaminated ambient air, and the patented condensate management system prevents condensate from penetrating the enclosure. A condensate evaporator is built in. Standard features also include R134a refrigerant, high capacity fans for continuous circulation, self-diagnostics on startup, LED fault indication and a thermostat, accessible from inside the enclosure, adjustable +77 to +113F (+25 to +45C) and factory set at +95F.

Overall dimensions are 17.13 in (435 mm) H x 23.43 in (595 mm) W x 19.49 in (495 mm) D with a 19.29 x 15.50 in (490 x 394 mm) cutout. At 117 lbs (53.07 kg) shipping weight, the DTT6401B460LG is the heaviest unit in its series. It comes with gasket, mounting kit, template, condensate drain hose and clamp, mounts with tool-less sash fasteners, and is finished in RAL 7035 powder-coated galvanized sheet steel. It maintains NEMA 12, is rated IP 54 and is UR, cUR and CE approved.
