DC Self-Regulating Heat Cable – Cut-to-Length (Up to 30 m) – 12V & 48V | Canada

This DC self-regulating heat cable is supplied in custom cut lengths, with a maximum continuous length of 30 metres per piece. It is designed for freeze protection in Canadian cold climates and for use in low-voltage DC systems such as solar battery banks, off-grid cabins, RVs, marine systems, and mobile power installations.

The cable is sold by the metre.

The self-regulating conductive polymer core automatically adjusts heat output in response to temperature changes, providing reliable freeze protection while reducing the risk of overheating—even when the cable overlaps itself.

⚠️ This product is supplied without factory-terminated ends.
Field termination and proper sealing are required.
