Purpose and fit
The Tempco EHR00014 is a silicone rubber enclosure heater rated at 120 W and 120 V AC for single-phase supply. It suits installers who need a low-profile heat source inside electrical cabinets or instrument enclosures. The built-in thermostat closes at 40 degrees F and opens at 60 degrees F to maintain a narrow temperature band. Buyers who require a different voltage, wattage or thermostat range should look elsewhere.
Thermals and power
The heater delivers 120 W of continuous heat and draws its power directly from a 120 V AC single-phase circuit. Its thermostat cycles the element on at 40 degrees F and off at 60 degrees F, limiting run time to the minimum needed for freeze protection. No fan or moving parts are present, so acoustic output is effectively zero during normal operation.
Build and connections
The flexible silicone rubber body measures 1/2 in high, 12 in long and 2 1/2 in wide with mounting holes on 9 in centres. A 48 in lead set is included for direct wiring to the supply. The assembly carries cURus recognition, confirming compliance with relevant safety standards for component-level use.

Questions about this item
How do I mount the EHR00014 heater and what is the common mistake with the hole spacing?
Mount using the 1/2 in height by 2 1/2 in width pattern with holes on 9 in centres; the frequent error is assuming the centres match the 12 in overall length instead of the specified 9 in dimension.
What part of the EHR00014 will need attention or replacement over time?
The built-in thermostat that closes at 40 degrees F and opens at 60 degrees F is the only moving component; plan to verify its switching action periodically and replace the heater if the thermostat drifts or fails.
What is the first limit reached when the EHR00014 runs continuously at full load?
The 120 W rating at 120 V AC is the steady-state ceiling; the thermostat will cycle at 60 degrees F, so sustained operation is limited by that fixed set-point rather than by overheating.
