Protection For Coils / Windings

Thermal Cut-outs/Bimetal Thermostats

THE F11 IS NOW F20A or F20B

This thermostat operates as a thermal cutout. A thermally sensitive bimetal snap-element with single contacts either opens or closes an electrical circuit by switching at a pre-set response temperature. Reset follows automatically after a considerable drop in temperature.

Heating by current

The diagram is measured with a thermal control without any insulation in an oil bath.
Attention:
The heating depends on the thermal conduction of the control to the equipment or part which should be protected.
