brand new and tremendous OOTDTY Features: The gadget protects the circuit from immoderate recent surges and excessive temperatures. When used, it is in series within the circuit. Under ordinary conditions, its resistance is small and the loss is small, which would not impact the traditional operation of the circuit. If an overcurrent (such as a quick circuit) occurs, its temperature rises. The resistance price increases sharply and reaches the restrict current to circumvent adverse the weather in the circuit. When the fault is removed, the temperature of the PTC mechanical device routinely drops and returns to the low resistance PTC Compressor Starter only, diversified package in the picture is not included!
