Notes
* Limitations may apply to the trace heater circuit length, in order not to exceed the maximum allowed operating current (steady state). Consult
the manufacturers trace heating system design documentation, containing the calculated operating current of the applicable trace heating circuit.
** PBTW is limited to use in trace heating circuits protected by a 16 A rated over current protection, see electrical data above.
# Maximum surface temperature of installation enclosures:
- with trace heaters installed and operating (with steady state operating current);
- with the installation enclosures positioned in the worst case orientation with maximum amount of accumulated dust layer (limitations to the ori-
entation of installation do not apply).
## Maximum sheath temperature trace heater, installed on workpiece.
### System comprising installation enclosure and trace heaters.
