Thermistor Relay
PT-01
Summary
PT-01 is an electronic relay for monitoring the temperature of motor. PT-01 thermistor relay is developed for PTC protection. When the temperature of motor coil exceeds the limit temperature of Tc-PTC, the output relay will be switched off immediately.
Refer to the figure below to understand the typical impedance of PTC temperature characteristics at three different switching temperatures (110, 120, 130). As shown in the figure, the PTC impedance is less than 100W when T < Tc-5, and T > Tc+5. C, PTC impedance greater than 10 kW |
