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.
