SSFR heating cable increases or decreases the heat output in a self-regulating way depending on changes in the ambient temperature, so a thermostat may not be necessary in some applications. It will never overheat or burn out even when overlapped. This heating cable reel is available with optional termination, power connection, splice and tee kits to reduce installation time and require no special tools.FEATURES:- Energy Efficient: Automatically varies its power output in response to temperature changes - Easy to install: Can be cut to any length (up to maximum circuit length) required on site with no wasted cable - Safe: Even when overlapped - Power Connection, Splice, Tee and End Seal Kit: Reduces installation timeMANUFACTURING:- Normal cable width 0.42 in. (10.6 mm)- Normal cable thickness 0.23 in. (5.8 mm)- Cable bus wire gauge 16 AWGINSTALLATION: - Maximum exposure temperature is 85 °C (185 °F)- Minimum installation temperature -40 °C (-40 °F)WARRANTY:- Two years
