The E4X/7-35235JB is designed for use as adjustable control thermostats for freeze protection and temperature maintenance applications requiring pipewall or tankwall sensing.

The design of the thermostats permits their use as a junction box for connecting the heating cable to power by using the optional mounting kit (TM4X for ordinary locations or TM7 for Division 2 hazardous locations).

Both thermostats feature an epoxy-coated cast aluminum NEMA 4X/NEMA 7 enclosure to provide watertight, dust tight, corrosion-resistant and explosion-proof protection to the thermostat switch. The differentiating factors between the two thermostats are the adjustable control range and maximum bulb exposure temperature.
