Thermostat and manually resettable thermal cut-offs

The tubular heating elements with dia. 8.5 mm can be equipped with a thermostat and a resettable thermal cut-off, mounted at the end of electrical tubular heating element. Heating elements with mounted thermal cut-off and/or thermostat are approved by SEMKO, VDE and UL, particularly suitable for liquid heating.

To determine the breaking temperature of the resettable cut-off it is advisable to measure the temperature under normal conditions and in intended application. The breaking temperature is recommended to be at least 25-30°C above the maximum temperature of the thermal cut-off at normal operation.
