For selecting the
calibration of the circuit
breaker, use the table on
the right, basing on the
model, on the length of
the installed
cable and
the minimum start-up
temperature. The
numbers in italic are the
cable maximum length.

The two copper conductors are located within an extrusion of a semi-conductive polymer (ETFE) whose resistance varies with temperature. The
characteristic is expoited to supply the required power in proportion to the process temperature and allows the
cable to be overlapped without
burning as the power reduces to almost zero as the polymer temperature limit is approached.
Poorly insulated
cable or
cable that cross insulation or voids will not be affected by such use. However it is important to ensure that the pipe
temperature does not exceed the maximum exposure temperature of the
cable either when operating or switched off.
For freeze protection or temperature maintainance up to 150 °C. For use in pipes, valves, tanks, etc.

for protection.
EExe II T4/T3*
(*): Area class depending on model, see above chart
-
Exposure temperature (even when switched off): minimum -40 °C, maximum +215 °C. Minimum bending radius: 40 mm.
Certifications (except for Base version): ATEX, FM, CSA, GOST for use in hazardous areas (EExe II T4/T3*).
Parallel construction allows the
cable to be cut on site and terminated and spliced by the installer.
