Capillary thermostat RT 8804
Description
Capillary thermostat RT is a single-pole temperature regulator based on the principle of liquid dilatation. It consists from two basic parts: switching unit and capillary temperature sensor. There is a protective earth pin on the cover. Regulated temperature can be user set in control range. Installation is made by two M4 screws. Product is VDE certified.Advantages
- variable location of temperature sensor in relation to position of switching unit
- switching unit can be installed in any position
- capillary can be bent according to installation need
- no consumption of electrical power
- low operating and servicing costs
