Working Principle 

Connect the PTC thermistor in series in the load circuit. When the circuit is in normal working condition, the current through the PTC thermistor is less than the rated current. The PTC thermistor is in the normal state and the resistance is small, which will not affect the normality of the protected circuit. jobs. When the circuit fails, the current greatly exceeds the rated current (2 times of the normal working current), and the PTC thermistor suddenly heats up, showing a high resistance state, so that the circuit is in a relatively "off" state for protection purposes. When the fault is removed, the PTC thermistor automatically returns to a low impedance state and the circuit resumes normal operation.
 
Application 

Inverter welding machine is more and more popular in the world since technoloy required for manufacturing. Good protection can assured inverter welding machine functioning well for long term.
