E4X-35235 and E4X-1 THERMON
The E4X-35235 and E4X-1 are designed for use as adjustable control thermostats for freeze protection and temperature maintenance applications requiring pipewall or tankwall sensing. E4X-35235 A nonmetallic NEMA 4X enclosure provides watertight, dust tight and corrosion-resistant protection to the thermostat switch. E4X-1 A nonmetallic NEMA 4X enclosure combines thermostat functions and heating cable power connection into a single unit that can be installed directly onto a heat-traced pipe (or to a nozzle protruding from a tank). The E4X-1 provides watertight, dust tight and corrosion-resistant protection to the thermostat switch while permitting one heating cable to enter through the mounting expediter.
FEATURES
- Pipe Sensing Thermostat
- Adjustable control thermostats for freeze protection and temperature maintenance applications
- Certified for use in ordinary (nonclassified) areas and hazardous (classified) locations
APPLICATION
The E4X-35235 and E4X-1 are designed for use as
adjustable control thermostats for freeze protection and
temperature maintenance applications requiring pipewall
or tankwall sensing.
E4X-35235 A nonmetallic NEMA 4X enclosure provides
watertight, dust tight and corrosion-resistant protection to
the thermostat switch.
E4X-1 A nonmetallic NEMA 4X enclosure combines
thermostat functions and heating cable power connection
into a single unit that can be installed directly onto a heattraced pipe (or to a nozzle protruding from a tank). The E4X1 provides watertight, dust tight and corrosion-resistant
protection to the thermostat switch while permitting one
heating cable to enter through the mounting expediter.
The E4X-35235 and E4X-1 thermostats are approved for
use in ordinary (nonclassified) locations.

Notes
1. The National Electrical Code, Article 427-56(b) states: “Temperature- controlled
switching devices which do not have an “off” position shall not be required to
open all ungrounded conductors and shall not be permitted to serve as the
disconnecting means.” The E4X-35235 and E4X-1 thermostats have no “off”
position and therefore may be used for switching one conductor of a two-phase
heating circuit.
2. The E4X-35235 and E4X-1 require a customer supplied fitting for connection to
power. The thermostats include an internal grounding terminal.
