  • Control switch can be located away from sensor
  • Switching capacity to 30 amperes
  • Capillary tube lengths up to 84″
  • Amperage switching capacity up to 30 amps depending on model and operating voltage
  • Double-pole, single-throw switching is standard
  • Capillary tube length of 84″ with bulb diameters of 1/4″ or 3/8″ depending on model
  • Temperature adjustment ranges of 0 °F (-18 °C) to 100 °F (38 °C), 60 °F (16 °C) to 250 °F (121 °C) or 100 °F (38 °C) to 550 °F (288 °C)
