brand new and wonderful OOTDTY Features: The device protects the circuit from immoderate current surges and high temperatures. When used, it is in series within the circuit. Under regular conditions, its resistance is small and the loss is small, which would not impression the normal operation of the circuit. If an overcurrent (such as a short circuit) occurs, its temperature rises. The resistance cost increases sharply and reaches the limit recent to bypass adverse the components in the circuit. When the fault is removed, the temperature of the PTC machine routinely drops and returns to the low resistance PTC Compressor Starter only, varied equipment within the picture is never included!
