Competitive Advantage:

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 voltage 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 "reaking up" to protect the circuit.

Product picture:


1. Surges due to lighting strikes on or near to the line plant.

2. Short-term induction of alternating voltage from adjacent power lines or railway systems, usually when these lines or systems occur fault.

3. Direct contact between telephone lines and power lines.
