Normally-closed thermal switches
These thermal switches are used for monitoring/controlling temperature without an electricity supply. With a normally closed relay, the circuit is broken upon reaching a defined temperature threshold or temperature that is too low within a predefined temperature range. The jump to an open or closed thermal switch always depends on the temperature. The circuit closes automatically within a desired temperature range.
Special models for specific applications are available on request.
Housing material and temperature ranges:
- Plastic (KO),
Temperature range -60°C to 200°C
- Ceramic (HCO/VCO/CO)
Temperature range -60°C to 390°C
- In compact housing (THO/TGO)
Temperature range -60°C to 200°C
The CO can be used for a rated voltage of 230 VAC to 16 A, in addition to rated voltages of up to 400 VAC / 16 A.
Degree of protection for the housing: IP 40
