Hammond DTT6301B230LG 5520 BTU/h 230V Top-Mount Enclosure Air Conditioner

The DTT6301B230LG is a 230 V, 50/60 Hz top-mounting air conditioner for electrical enclosures, part of the DTT 4000-7000 BTU/H indoor series. It gives panel builders and maintenance engineers 5520 BTU/h (1620 Watts) of cooling at +95/+95F (+35/+35C) in a unit that sits on the enclosure roof, freeing the side walls for other equipment. Its short description lists it as a 5300BTU model.

On the electrical side, the unit is rated 230 V (+/- 10%) at 50/60 Hz and consumes 980/1140 W. Running current is 5.73 / 7 A and starting current is 19.7 / 23.2 A. Power is connected through a terminal block with plug. A provision for a door contact lets the unit power down when the enclosure door is opened, and the hot gas bypass valve prevents evaporator freeze up while minimizing heavy inrush currents.

Cooling is closed loop, so enclosure air is recirculated without mixing with contaminated ambient air. The patented condensate management system keeps condensate out of the enclosure and a condensate evaporator is built in. R134a refrigerant, continuous air circulation from high capacity fans, self-diagnostics on startup and LED fault indication are standard. The thermostat adjusts +77 to +113F (+25 to +45C) from inside the enclosure.

Dimensions of the DTT6301B230LG 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. It ships at 93 lbs (42.18 kg) and includes gasket, mounting kit, cutout and drilling template, condensate drain hose and clamp; mounting uses tool-less sash fasteners. The galvanized sheet steel housing has a RAL 7035 powder finish. It maintains NEMA 12, is rated IP 54, carries UR, cUR and CE, and operates in +59 to +131 F (+15 to +55 C) ambients.
