Barksdale's THR & THL Series Temperature Switches
Series THR, THL
Description
Barksdale's THR & THL Series Temperature Switches add flexibility to Barksdale's solid reputation for quality & reliability and offers versatility for your temperature switching needs. These thermostats are ideal for freeze protection or temperature control in more demanding industrial applications. The THR & THL Series thermostats feature 10 foot stainless steel sensors for remote monitoring and local mount sensors for ambient temperature sensing. The THR & THL 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 THR & THL Series models are all UL listed & CSA approved.
