Switching temperature
Choose the appropriate switching temperature between -30 and 450 °C.
Possible to set reduced tolerances and special differential.

More safety with electrical self-holding
The electrical self-holding prevents self-reset in case of thermal overload caused by equipment failure.
Equipment must be first detached from power in order to allow the switch to reset.

Nimble cutoff thanks to additional current sensitivity
Current sensitivity reached by additional serial resistance or using bimetal discs with different inner resistance.
Cutoff before the application reaches critical temperature.
Practical placement of the switch far from the temperature source.
