 The
F11 is now F20A or F20B
F13, F20, F23
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.

Generators, Convertors, Transformers, Pumps, Heating
Elements, Signal Transmitters, Fire Detectors, Magnets,
Relays, Chokes, Coils, Power Supplies, Inverters
Benefits
- Small dimensions
- Shock and vibration tested
- Leadframe version

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. |
