Temperature Switch Single-Stage Fixed Deadband, Open Frame Watertight Enclosure, Fixed Deadband At Mid-Range (4°F) 15.5°C , SPDT, 15 Amp Res., 125 VAC , 10 Amp Res., 250 VAC c/w KD11A1 Temperature Transducer Unit , 6 Foot Copper (CU) Capillary and Bulb.

Features:
• PB Switch Unit Single-Stage Fixed Deadband units have an adjustable set point and a non-adjustable automatic reset point
• P-Series watertight switch enclosures are epoxy-painted, zinc coated steel with a 1/2” conduit hub in the side of the lower housing for electrical entry
• When pressure is applied to the transducer it is converted into movement of the piston. This piston movement is then used to control the operation of the electrical snap-action switch in the switch unit.
• The temperature transducer works on the vapor principle where the internal pressure within the system is generated by the vapor pressure of a chemical within a sealed system
• The temperature sensed by the bulb is related uniquely to an internal pressure within the system
• The pressure acts on a diaphragm/piston to create the force output from the transducer into the switch unit
