Hammond FLHTF1300A115 1300W 120V Enclosure Fan Heater, 50 CFM Thermostat

The FLHTF1300A115 is a fan-forced enclosure heater with a built-in thermostat, rated 1300 W on 120 V, 60 Hz and moving 50 CFM. It is designed to prevent condensation or maintain a minimum temperature inside a control panel or metal enclosure, protecting critical components from freezing and condensation. It is not intended as a comfort or space heater.

As one of the 1300 W models in the FLH series, it has the larger housing at 7.5" x 5.6" x 6.9" (H x W x D) in the ordering table, with 189.87 mm [7.475 in] x 141.61 mm [5.575 in] x 173.86 mm [6.845 in] shown on the drawing, and it moves more air than the smaller sizes. Its approval is cURus/cULus only: the drawing lists cULus Recognized to UL 508A and C22.2 No. 14-13.

The outer casing is aluminum alloy. The adjustable thermostat covers -18 C to +38 C (0 F to +100 F), and a Fan Auto/On switch with pilot light shows when heat is on. In FAN mode the fan runs continuously for more uniform temperature distribution and heat is still provided below the set point; in AUTO mode the fan cycles on only when the heating element is energized. An automatic reset temperature limit switch breaks power to the element on fan failure or overheat.

Mount the FLHTF1300A115 vertically inside a metal enclosure on a metal surface, terminal block at the bottom and discharge vents at the top, using four #10 metal screws, as low and central as possible. Keep heat-sensitive components clear of the vents by the FLHTF1300 clearances (10in / 250mm X, 4in / 100mm Y). Wiring is by qualified personnel with wire rated at least 90°C; there is no OFF position, so disconnect supply power to shut it down.
