SKU: SSS-DC-HEAT-12V-1MT
DC Self-Regulating Heat Cable – 12V– Pre-Terminated (3m / 5m / 7m) | Canada
This DC self-regulating heat cable is designed for reliable pipe freeze protection in Canadian cold climates, operating on 12V DC power. It is ideal for solar battery systems, off-grid cabins, RVs, marine applications, and mobile power systems where AC heat tracing is not practical or available.
Each cable is supplied in fixed cut lengths with factory-terminated positive and negative leads, allowing for fast, clean installation without cutting, splicing, or field termination.
The self-regulating conductive polymer core automatically adjusts heat output as temperatures change, delivering efficient freeze protection while preventing overheating—even when the cable overlaps itself.
Key Features
-
Available in 12V DC
Designed specifically for low-voltage DC systems, commonly used across Canadian solar, RV, marine, and off-grid installations.
-
Pre-Terminated DC Leads
