4X/7-350235JB Control Thermostats

The 4X/7-350235JB, equipped with a double-pole switch, is designed for use as an adjustable control thermostat for freeze protection and temperature maintenance applications requiring pipewall or tankwall sensing. The design of the thermostat permits its 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). The thermostat features 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

FEATURES

• Epoxy- coated cast aluminum NEMA 4X/NEMA 7 enclosure
• Adjustable control thermostats for freeze protection and temperature maintenance applications
• Certified for use in ordinary (nonclassified) areas and hazardous (classified) locations

APPLICATION
The 4X/7-350235JB, equipped with a double-pole switch,
is designed for use as an adjustable control thermostat
for freeze protection and temperature maintenance
applications requiring pipewall or tankwall sensing. The
design of the thermostat permits its 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). The thermostat
features an epoxy- coated cast aluminum NEMA 4X/NEMA
7 enclosure to provide watertight, dust tight, corrosionresistant and explosion proof protection to the thermostat
switch.
The 4X/7-350235JB thermostat is approved for use in
both ordinary (nonclassified) and hazardous (classified)
locations.
