Features of Raychem CCH-2C 208 to 277 Volt Self-Regulating Crankcase Heater

When compressors operate in cold areas, the refrigerant can migrate into the crankcase oil whenever the compressor is not running. This can cause excessive motor wear and a loss of refrigeration efficiency during compressor start-up. nVent RAYCHEM FreezGard self-regulating crankcase heaters provide reliable peak heating during critical cold periods and, unlike conventional constant-watt heaters, reduce their heating output once the compressor starts up or the air temperature rises. Self-regulating heating cable can also be safely overlapped and closely spaced without burning out. One size fits all hermetic compressors up to 5 HP that are 40 inches or less in circumference. Models for both 120 V and 208 to 277 V are available. Each comes with a flexible lock-strap and pre-stripped 28-inch cold leads for easy connection and hard-wiring. Use only with refrigeration compressors in nonhazardous areas.

Ground-Fault Protection

To minimize the danger of fire from sustained electrical arcing if the heating cable is damaged or improperly installed, and to comply with the requirements of nVent, agency certifications, and national electrical codes, ground-fault equipment protection must be used on each heating cable branch circuit. Arcing may not be stopped by conventional circuit protection.
