Capacitors Relays and motors w5 Flashcards | Quizlet Smooth out the current Current Relay. False, A time-delay fuse may allow a motor to be damaged from high current before the time delay is over. Tip: Use a toothbrush to clean any dust from around the ports if the reading didnt change, and then take another reading. c. Watts False, An internal bimetal protection device will open the motor circuit when the temperature reaches 200F to 250F (93C to 121C). In the PTC relay the supply goes direct to the run winding but between the supply and start winding a thermistor is connected in series and when we switch on the refrigerator the current start flowing through the thermistor to the auxiliary and compressor start-up, this current flows heat thermistor and due to temperature, the resistance of thermistor high and thermistor remove the start winding from the supply. This refers to the silicon guts inside the relay whose resistance increases as its temperature rises. This will allow full-line voltage to the start winding during start-up, giving the motor a stronger phase shift to get started. d. Source Voltage, Testing the coil of a relay with an ohm meter provides an infinity reading. PTC Thermistor Motor Starter - AMWEI Thermistor Sensor d. series,start. As I wrote above that PTC means a positive temperature coefficient thermistor which means that a relay with working relation with temperature.
