Chromalox 512129-CPR5-1CR Heat Trace Cable 5w/ft 120V

Product Description

The CHROMALOX 512129-CPR5-1CR is a self-regulating heat trace cable rated at 5 watts per foot at 120 volts. It is built around a self-regulating polymer core that automatically adjusts heat output based on the ambient temperature sensed along its entire length, preventing overheating and reducing energy use during warmer conditions. The outer jacket is a TPR polyolefin overjacket applied over braid, providing resistance against certain inorganic chemical solutions. Licensed electricians and fire protection contractors install this cable in commercial and residential applications where freeze protection, de-icing, or supplemental heating is required.

This cable is engineered for a broad range of heat tracing applications. Common uses include commercial pipe heating, fire sprinkler pipe freeze protection, roof and gutter de-icing, and underslab heat loss replacement. The cable can be cut to length in the field, spliced, and teed to follow complex piping layouts. It can also be routed inside conduit, which allows future cable replacement without disturbing the installation. On roofs and in gutters, it prevents ice dam formation and maintains a clear path for meltwater drainage. When embedded in concrete slabs or placed beneath slabs, it counters frost heave and provides supplemental comfort heat.

Key Features

• Self-regulating polymer core adjusts output along the full cable length, reducing hot spots and energy waste
• Rated 5 watts per foot at 120 volts for reliable low-voltage freeze protection
• TPR polyolefin overjacket over braid resists certain inorganic chemical solutions
• Field-cuttable and spliceable to fit straight runs, tees, and complex piping networks
• Compatible with conduit installation, enabling cable replacement without excavation or pipe disassembly
• Suitable for embedded concrete, roof and gutter, and exposed pipe applications

Compatibility

This cable is identified as a possible alternative or replacement for heat trace cables from other manufacturers, including models 5XL1-CR, 5XLE1-CR, GM-1X, 5-FLX-1-OJ, CLT5-JT, and TSR51J. Compatibility with a specific application must be confirmed by the installer or end user prior to installation. CHROMALOX is not the authorized distributor for those referenced manufacturer lines.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for electric heat tracing systems. De-energize and lock out all circuits before handling or modifying the cable assembly. When embedding in concrete or routing in conduit, verify the cable jacket rating is appropriate for the chemical environment and installation conditions. Do not overlap the cable on itself during installation, as this can affect the self-regulating performance.
