Application
The Thermon B7-15140 is designed to provide ambient sensing control of electric heat tracing circuits for freeze protection of piping and vessels. This adjustable thermostat can be used to control a single heating circuit or as pilot control of a contactor switching multiple heat tracing circuits. The B7-15140 has an aluminum lacquer finished die-cast aluminum enclosure provides NEMA 4X (water tight, dust tight, and corrosion resistant) and NEMA 7/NEMA 9 (explosion proof) protection to the thermostat switch. The tamper-resistant, threaded and gasketed aluminum dial cover is externally adjustable.
The B7-15140 is approved for use in both ordinary (nonclassified) and hazardous (classified) locations.
