Raychem 734921-000 Self-Regulating Heating Cable 250 ft 120VAC

SKU CH-J5XS-S0AS9

Self-regulating heating cable delivers 6 W per foot at 40 °F across 250 ft of 120 VAC rubberized polymer for freeze protection down to -40 °F

  • Product typeTarps
  • Self-regulating output adjusts automatically to ambient conditions
  • 250 ft continuous length allows custom cut-to-fit installations
  • 120 VAC supply works with standard North American power
  • Hardwired connection eliminates plug-related failure points
  • Operates from -40 to 150 °F for extreme-environment reliability

Cut-to-Length Heating Cable for Pipe Protection

This 250 ft roll of self-regulating heating cable is designed for indoor and outdoor freeze protection on pipes and vessels. It operates at 120V AC and adjusts its heat output automatically based on the surrounding temperature. The cable is cut to the exact length required on site, reducing waste during installation. It suits maintenance teams and facility managers who need reliable trace heating without complex controls.

Hardwired Connection and Conductive Core

The cable includes only the heating element itself and requires hardwiring into a suitable junction box or control panel. Its conductive carbon core delivers 6 watts per foot at 40 degrees F, drawing 0.05 amps per foot at the same temperature. The rubberized polymer cover protects the two conductors from moisture and mechanical damage. No plug, thermostat or termination kit is supplied in the box.

Durable Polymer Jacket for Harsh Environments

The rubberized polymer jacket withstands operating temperatures from minus 40 to 150 degrees F, making it suitable for unheated spaces and exposed pipework. Maximum circuit length is limited to 200 ft, so the 250 ft roll must be split into multiple protected circuits. The two-conductor construction simplifies wiring but requires careful planning for end seals and power connections. Installers who need pre-assembled kits or integrated controls should look elsewhere.

Questions about this item

How often will the rubberized polymer jacket need inspection or replacement after outdoor installation?

The rubberized polymer jacket is rated for continuous exposure from -40 to 150 degrees F; inspect annually for mechanical damage or UV degradation and replace any cracked sections.

What limits the maximum single circuit to 200 ft when the reel contains 250 ft?

The 200 ft maximum circuit length is set by voltage drop on the conductive carbon core at 120 VAC; longer runs would fall below the 6 W per foot output at 40 degrees F.

What surface temperature and power draw should I expect after the cable has been energised all day at 40 degrees F ambient?

At 40 degrees F the cable stabilises at its 6 W per foot rating, drawing 0.05 A per foot, and the outer jacket remains well below the 150 degree F maximum operating temperature.
