When the switch is opened, the current flows through the PTC heating resistor and heats the switch so that it remains switched off until the voltage is removed. The series resistor is used to adjust the current sensitivity, as its heating causes the switch to trip earlier. |

Hint
The data and information provided are based on tests and test series. They are intended as a guide, which is why there may be deviations for individual applications and uses. The suitability for a specific application must be checked by the user in each individual case. We will of course be happy to advise you.
