19P Current Limited 19MM 100OHM Welding Machine Positive Temperature Coefficient PTC Thermistor
Brief Introduction
Function:PTC Thermistor Special for over current,overload protection of welding machines.
MZ31 series 15P,16P,19P PTC thermistor are million- time safety thermistor of automatic circuit protection,recoverability, using repeatedly, and no trigger, noise or protective component that could protect and restore from abnormal temperature and current automatically,which called "auto restore fuse" and "ten-thousand-time fuse".Recoverability, using repeatedly, and no trigger, noise or sparks.
The above three models are all used for overcurrent overload protection of welding machines, just different welding machine size use different PTC thermistor Model.
Working Principle
When the circuit is in normal state, the current passing through the PTC thermistor is less than the rated current, and the PTC thermistor is normal and the resistance is small.Does not affect the normal operation of the protected circuit. When the circuit fails and the current greatly exceeds the rated current, the PTC thermistor suddenly heats up and is in a high resistance state. The circuit is disconnected to protect the circuit from damage. When the failure is eliminated, the PTC thermistor automatically returns to a low resistance state and the circuit returns to normal operation.
