Thermal Switch Assembly


The Thermal Switch Assembly is required to be installed on all Hydraulic Power Units, per ASME A17.1/CSA‐B44, 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.
