Self-Regulating Crankcase Heater 120V
This self-regulating crankcase heater operates at 120 V AC and delivers a minimum of 60 W. It activates automatically when the temperature reaches 0 °F to protect compressor crankcases in HVAC and refrigeration systems. The 48 in black heating cable includes a power cable without a plug for hard-wired installation. It carries cULus certification for safety compliance.
Thermals and Power Draw
The heater self-regulates its output based on ambient conditions, drawing at least 60 W only when the temperature falls to the 0 °F trigger point. This behaviour limits unnecessary power consumption and reduces thermal stress on the crankcase. No fan or moving parts are present, so operation is silent. The unit is designed for continuous duty in the environment where it is installed.
Installation and Build Fit
The 48 in cable length determines the reach from the power source to the crankcase, so installers must verify routing space before mounting. A power cable without a plug is included, requiring a suitable junction box or hard-wire connection supplied by the installer. The heater frees the system from manual cycling and eliminates the need for an external thermostat. Buyers who need a factory-fitted plug or a different activation temperature will require a different solution.

Questions about this item
How is the 48 in self-regulating crankcase heater installed, and what step is often missed?
Wrap the heating cable around the compressor crankcase and secure it with the included power cable; the step often missed is ensuring full contact along the 48 in length so the self-regulating function can sense temperature evenly.
What maintenance or replacement will the 60 W heater need later?
Inspect the black heating cable annually for cracks or insulation damage; replace the unit if the self-regulating element no longer activates at 0 Degrees F or if the power cable shows wear.
What limit appears first during sustained operation of the 120V AC heater?
The self-regulating design caps output at 60 W once the crankcase reaches the set point, so the thermal limit — not voltage or cable length — is the first constraint under continuous use.
