Hammond DTS3661C460N3LG 25,930 BTU/h 460V NEMA 3R Side-Mount Air Conditioner

Delivering 25,930 BTU/h (7,593 W) at +95/+95°F (+35/+35°C), the DTS3661C460N3LG is the highest-capacity light gray unit in this outdoor range and runs on a 460 V 50/60 Hz supply at 5.18 A. It is intended for side mounting on large outdoor control enclosures where engineers want closed-loop cooling with a modest starting current of 10 A.

The unit is designed for side mounting on any enclosure surface where high capacity system cooling is required. Closed loop cooling recirculates clean enclosure air without ever mixing it with contaminated ambient air, and the layout keeps maximum clearance between the warm inlet and cold outlet to reduce hot spots. The condenser uses 3 mm fin spacing for protection against strongly contaminated and aggressive ambient air, and the unit runs filterless. The exterior case is galvanized sheet steel finished in RAL7035 light gray; an ANSI 61 gray version is available by replacing LG with GY in the part number.

Electrically, DTS3661C460N3LG is rated 460 V 50/60 Hz with an operating range of 414-506V, power consumption of 3060W, running current of 5.18A and a starting current of 10A, connected via terminal block. It circulates 1277 CFM internally and 813 CFM externally (unrestricted), uses 450 g of R134a refrigerant, and its thermostat is adjustable from +77 to +113°F (+25 to +45°C) with a factory setting of +95°F (+35°C). It operates in ambient air from +25°F (-4°C) to +131°F (+55°C) at a noise level of 81 dB(A).

Overall size is 57.2 in x 15.8 in x 16.1 in (1,453 mm x 401 mm x 409 mm) H x W x D, and the unit weight is 234.8 lbs/106.5 kg. Gasket, mounting kit and a template for the enclosure cutout and drilling are included, along with a condensate drain hose and clamp; a built-in condensate evaporator handles condensate discharge. The series carries UL, cUL and CE approvals, complies with IP56 and NEMA 3R, 4, 4X, and this part is listed as RoHS and REACH compliant.
