brand new and high-quality OOTDTY Features: The formula protects the circuit from excessive recent surges and excessive temperatures. When used, it is in series within the circuit. Under usual conditions, its resistance is small and the loss is small, which would not affect the ancient operation of the circuit. If an overcurrent (such as a quick circuit) occurs, its temperature rises. The resistance price will increase sharply and reaches the restrict 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, different equipment in the photograph isn't always included!
