      Description 
      
        
      Barksdale's TPR Series Temperature Switch adds flexibility to Barksdale's solid reputation for quality & reliability, and offers versatility for your temperature sensing needs. This switch is ideal for applications where freeze protection or lower temperature control is critical. The TPR is available in factory set and locked NEMA 4X configurations. The tin-plated sensor comes in 3 or 10 foot lengths. The TPR Series feature limit switches with 22 amps @ 125/250 VAC and 3 amps @ 480 VAC electrical ratings that allow thermostats to be used for higher current, heat tracing applications. The TPR Series is UL listed and CSA approved.
