Selection Guide of 16P PTC thermistor

When selecting a PTC thermistor for welding machine overload protection, consider the operating voltage, current requirements, dimensions and specific application needs to ensure optimal protection and performance.

PTC thermistor 16P Working Principle

When the circuit is operating normally, the current passing through the PTC thermistor, such as the PTC 16P, is below the rated threshold. In this state, the PTC thermistor maintains a low resistance, allowing the circuit to function without disruption. However, if a fault occurs and the current significantly exceeds the rated level, the PTC thermistors rapidly heats up, transitioning to a high-resistance state. This sudden increase in resistance effectively disconnects the circuit, protecting it from potential damage. Once the fault is resolved, the PTC 16P thermistor automatically cools down and returns to its low-resistance state, allowing the circuit to resume normal operation.

This automatic response ensures continuous protection without the need for manual intervention, making PTC 16P thermistor a reliable component in safeguarding electrical circuits from overcurrent and overload conditions.
