The Pelco WD57-1 is a window defroster module for use with an EH5700 series enclosure. With this defroster installed, the viewing window on the housing will remain clear from fog and ice during cold or high humidity conditions. If you are installing this defroster for the first time inside a basic housing (EH5723 or EH5729), you'll also need to get the PC Board Assembly with Thermostat (O/I-PCB).
Note! Requires PC Board Assembly accessory (O/I-PCB)
