Ranco A30-3952 Thermostat Kit W/Cold Cutout Bulb Holder 48" CAP & 5/16" ID X 14" Tube

The Ranco A30-3952 Thermostat Kit is a commercial temperature-sensing and control assembly featuring a cold cutout bulb holder, 48-inch capillary, and 5/16-inch inside diameter by 14-inch tube. Installed in compatible temperature-controlled equipment, the sensing bulb monitors conditions at the designated area while the capillary transfers the thermal response to the thermostat mechanism. The thermostat changes its electrical contact state when the sensed temperature reaches the selected control point, allowing connected circuit to cycle accordingly. The bulb holder and tube provide required positioning for the sensing assembly. It works with the equipment wiring and controlled component as part of the temperature-regulation system.
