S1 and S2 – 12 Watt/foot High Performance Self-regulating Heater Cable Construction, Specifications, and Approvals

Summit Ice Melt heat tape prevents ice dam leaks

Summit’s S1 (120Vac) and S2 (208-277Vac) 12 watt/foot heater cables are industrial grade, self-regulating heaters. Customers can be assured that they are getting the highest quality product from a company that has the most extensive experience in designing roof and gutter de-icing systems.

The cables are comprised of two parallel nickel-coated bus wires in a cross-linked polymer core, a tinned copper braid and a heavy duty protective polyolefin outer jacket. They meet or exceed all established industry standards as indicated below.

The cables are used in Summit’s ice melt systems, extend into gutter and downspout systems, and are controlled in conjunction with the ice melt system. The combination of the Summit Ice Melt Systems, with heated gutters and downspouts provide the ultimate in ice and meltwater management in snow country.
