Johnson Controls A19ABC-83 SPDT Averaging Bulb 6" Capillary with 8" 100°F-300°F

The Johnson Controls A19ABC-83 is a single-stage, remote bulb temperature control used for controlling heating or cooling equipment according to the temperature sensed at a distance. It comprises a sensor bulb that is linked to a switch through a 6” capillary tube and is housed in a NEMA 1 enclosure. The switch is activated when the temperature around the bulb is between 100°F and 300°F and the differential between the two is set at between 7°F and 28°F by the user. It can then switch on or off any heating or cooling equipment to maintain the set temperature by employing this SPDT switch.
