RTKSA-014.210
Universal capillary double thermostat, TW 0…120…°C, TW 0…120…°C, hysteresis 2x 3K
This series of devices was specially developed for use in heating technology in boiler systems or storage tanks, district heating transfer stations and heat transfer systems, in ventilation technology as supply air monitors or as limiters for electric heating registers. Immersion sleeves/protection coils are not included in the scope of delivery. The JZ-30 accessory must be used in conjunction with immersion sleeves or protection coils.
The control range / hysteresis for both temperature monitors is 0… 120 ° C / 3K.
Art.-Nr.: KA001100
