OEM ODM PTC Ceramic Heater , PTC Thermistor For Overcurrent And Overload Protection
Features
1. PTC thermistor for overcurrent and overload protection is a million-time device of
automatic protection, recoverability, using repeatedly, and no trigger, noice or sparks.
2. When PTC is in the normal state, the resistance is too low to affect the regular work of
the protected circuit such as the volatge transformer's primary and secondary loops.
3. When the circuit is in disorder, the PTC will generate heat suddenly, and the resistance
value will go up to the high state, which make the circuit in the state of relatively "breaking up" to protect the circuit.
