Temperature Protection Relay - TPR6-14


The TPR6-14 monitors 1-14 RTD/Thermistor temperature inputs. It accurately measures
the temperature increase to protect the motor / transformer from damage due to heat
build-up in the windings and / or bearings. The built-in self test protects against disconnected
sensors and operator faults.
