Thermon E4X-1

Adjustable Control Industrial Heating Thermostat


The Thermon E4X-1 is ingeniously designed to combine thermostat functions and heating cable power connection into a single unit, streamlining installation directly onto heat-traced pipes or tank protrusions. Crafted with a nonmetallic NEMA 4X enclosure, it ensures watertight, dust tight, and corrosion-resistant protection to the thermostat switch while facilitating the entry of one heating cable through the mounting expediter. Approved for use in ordinary (nonclassified) locations, the E4X-1 offers a convenient and reliable solution for freeze protection and temperature maintenance applications requiring pipewall or tankwall sensing.
