Construction

Thermon FP: Parallel Constant Watt Heating Cable, product specifications

  1. Copper bus wires (12 AWG)
  2. Nichrome heating element
  3. Heater bus connection (not shown)
  4. Fiberglass overlay
  5. Fluoropolymer dielectric Insulation.
  6. Tinned copper braid
  7. Fluoropolymer overjacket provides additional protection
    for cable and braid where exposure to chemicals or
    corrosives is expected.

Applications for Thermon FP Parallel Constant Watt Heating Cable

FP parallel resistance constant watt heating cables are designed to provide freeze protection or process temperature
maintenance to piping, tanks and equipment.

The parallel resistance configuration allows the cable to be cut to length and terminated in the field with easy-to-use Thermon
supplied kits.

FP cables provide consistent and reliable heat outputs regardless of circuit length. FP cables are not subject to the inrush current associated with self-regulating heating cables, therefore the need for over sizing power distribution equipment is eliminated.

FP cables are approved for use in ordinary (nonclassified) areas, hazardous (classified) areas and Zone 2 classified
areas.

Notes:

¹Additional operating voltages are shown below
²T-rating per internationally recognised testing agency guidelines.
³Thermon heating cables are approved for the listed T-ratings using the stabilised design method. This enables the cable to operate in hazardous areas without limiting thermostats. The T-rating may be determined using CompuTrace® Electric Heat Tracing Design Software or contact us for design assistance.

Circuit Breaker Sizing and Type

Maximum circuit lengths for various circuit breaker amperages are shown below. Breaker sizing should be based on the National Electrical Code or any other applicable code. The National Electrical Code require ground-fault protection of equipment for each branch circuit supplying electric heating equipment. Check local codes for groundfault protection requirements.
