it utilizes a negative biased power element diaphragm to ensure the circuit interrupts power immediately upon reaching the calibrated threshold

making it suitable for a wide range of fractional and integral horsepower compressors

Industrial-Grade Construction: Built with high-quality materials to withstand the thermal stress of continuous heating and cooling cycles

excessive soot buildup on the cell face can "blind" the detector

protecting the compressor from damage
