Raychem 20QTVR2-CT Self Regulating Trace Heating Cable
Electrical heat-tracing for process temperature maintenance applications up to 110°C which are not subject to steam cleaning.
The nVent RAYCHEM QTVR family of self-regulating, parallel circuit heating cables is used for process temperature maintenance of pipes and vessels.
It can also be used for frost protection of large pipes and for applications requiring medium temperature exposure capability.

Maximum Circuit Length
Based on Type 'C' Circuit Breakers According To EN 60898
|Electrical Protection Sizing||Start Up Temperature||Maximum Heating Cable length per circuit(M)|
The above numbers are for circuit length estimation only. For more detailed information please use the Pentair TraceCalc software or contact your local Pentair representative.
Pentair requires the use of a 30 mA residual current device to provide maximum safety and protection from fire.
Where design results in higher leakage current, the preferred trip level for adjustable devices is 30 mA above any inherent capacitive leakage characteristic of the heater as specified by the trace heater supplier or alternatively, the next common available trip level for non adjustable devices, with a maximum of 300 mA. All safety aspects need to be proven.
