This is a replacement toggle switch for Polar Cool 48" evaporative coolers that run on 240V. It controls the fan motor and the pump, and it's the part you need when the original switch on the control panel fails or sticks.
This DPST toggle switch replaces the original control on Polar Cool 48" evaporative coolers wired for 240V. It's built to stand up to the vibration and duty cycles typical of warehouse and outdoor cooling equipment, where switches see frequent on/off cycling over a season. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
