Specification
Stem thermostats THS 90/210 are designed for operation of electric appliances depending upon temperature of measured medium.
Mounting is performed into heating system using copper protection well with thread G1/2. Suitable material is used for joint sealing, preferably teflon tape. Maximum permissible pressure on the well 10bar (1 MPa).
Made in wide range of temperature ranges. Standard stem length 100mm (in case of need 200, 300mm). Stem thermostats DTHS 70/90 with PPTC fuse are designated for thermoregulation in liquid or other environment. In case of thermostats failure, the thermostats fuse automatically switches-off the circuit.
The fuse is part of this device. Fuse serves purely as a protection element, which may be manually turned-on after case removal or the automatic reset with t 20°C may be used.
