The Thermal Switch Assembly is required to be installed on all Hydraulic Power Units, per ASME A17.1/CSA‐B44 3.26.6.5, to prevent the oil temperature from rising above its maximum operating temperature. This assembly can be used in both Submersible and Dry Power Units.
The switch is factory pre‐set at a temperature setting of 145º F (63º C) and will fit in a tank up to 44" tall. Conduit length is 19" and can be trimmed if necessary for a shorter tank. For more information on the electrical characteristic of the switch see Sales Bulletin SB‐026.
