Capillary thermostat RT 8803

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 earht pin on the cover. Regulated temperature can be user set in control range. RT can be also used as anti-frost fuse. Installation is made by two M4 screws.
