SRFF(s) SERIES
Self-Regulating Heating Cable for Freeze Protection of Pipework
Fine Korea SRFF(s) Series Pre-assembled self-regulating heating cable are designed for residential metal and plastic on/in pipes freeze protection applications.
SRFF(s) Series are available up to 175 ft lengths(54M), and each comes assembled with a 3.3ft(1M) or 5.9ft(1.8M) power cord and plug. SRFF(s) Series are ideal for smaller jobs such as pipe freeze protection on/in pipes up to 2-1/2 inches(63.5mm) in diameter.
FINE SRFF(s) Series generates heat by a material of semi-conductor, showing a characteristic of PTC (Positive Temperature Coefficient). It produces more heat if the temperature drops and less heat if the temperature rises.

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 Fine Korea, agency certifications, and national electrical codes, 30-mA equipment or 5-mA personnel ground-fault protection must be used on each SRFF SERIES heating cable branch circuit. Arcing may not be stopped by conventional circuit protection.
