Purpose and target users
The Value Brand SCH-2CR is a self-regulating crankcase heater designed for HVAC compressors. It prevents refrigerant migration during off-cycles in cold ambient conditions. The unit suits residential and light-commercial air-conditioning or heat-pump systems that require reliable cold-weather protection.
Capacity and headroom
The heater delivers a minimum of 60 watts across a 48-inch heating cable. It activates automatically when the surrounding temperature reaches 0 degrees Fahrenheit and modulates output as conditions warm. The 208 to 277 volt AC range covers common single-phase and three-phase supply voltages found in North American equipment.
Installation fit
The assembly includes a power cable without a plug, allowing direct wiring into the equipment control panel or a dedicated junction box. The black, cULus-listed construction resists moisture and oil exposure typical of compressor housings. No thermostat or external controller is required, freeing up control-circuit space and simplifying the installation.

Questions about this item
Will the 208-277 V self-regulating heater work with an older 240 V compressor circuit?
Yes, the heater is rated for 208 to 277 V AC and operates at 240 V, so it connects directly to existing 240 V supply wiring without modification.
How can I confirm the 60 W cable is heating correctly once installed?
The unit turns on automatically at 0 °F; verify operation by measuring current draw at the power cable when ambient temperature is at or below that point.
Does the 48 in black heating cable come with a plug or only the power cable?
The package includes the heating cable and a power cable without a plug; a suitable plug or hard-wire connection must be supplied separately.
