Hammond DTS3261A460N3LG 6,825 BTU/h 460V NEMA 3R/4 Side-Mount Air Conditioner

The DTS3261A460N3LG delivers 6,825 BTU/h (2,000 W) of side-mounted cooling for outdoor enclosures fed from 460 V 50/60 Hz, drawing 2.6 A running and 16 A starting. With IP56 and NEMA 3R, 4 compliance, it serves outdoor industrial control panels where engineers want larger-capacity closed-loop cooling on a 460 V supply.

Designed for side mounting on any enclosure surface, the unit uses closed loop cooling so clean enclosure air is recirculated without ever mixing with contaminated ambient air, and it keeps maximum clearance between the warm inlet and cold outlet to reduce hot spots. The exterior is NEMA 3R/4 galvanized sheet steel with a powdercoat finish in RAL7035 light gray; an ANSI 61 gray version is available by replacing LG with GY. An expansion valve prevents evaporator freeze up while minimizing heavy inrush currents.

DTS3261A460N3LG is rated 460 V 50/60 Hz with an operating range of 360-506 V, consumes 1400 W, and draws 2.6 A running and 16 A starting, wired through a terminal block. It carries a 700 g charge of R134a refrigerant, moves 450 CFM internally and 450 CFM externally (unrestricted), and uses a 150 g/m² filter mat. The thermostat, accessible from inside the enclosure, adjusts from +77 to +113°F (+25 to +45°C) with a factory setting of +95°F (+35°C). Rated ambient range is +32°F (0°C) to +131°F (+55°C), with a noise level of <73 dB(A).

Unit weight is 123 lbs (56 kg) and shipping weight is 99 lbs (44.91 kg). Gasket, mounting kit and template for the enclosure cutout and drilling are included, as are a condensate drain hose and clamp, and a built-in condensate evaporator handles condensate discharge. Self-diagnostics run on startup, faults are shown by LED, and a door contact provision allows power down when the enclosure door is opened. The series carries UL, cUL and CE approvals and complies with NEMA 3R, 4 and IP56. This part is listed as RoHS and REACH compliant.
