Product Description
PTC component and contact circuit form a parallel circuit. With the heading up of temperature, contact circuit is off and current flows through PTC component to form a loop. The temperature of PTC component increases rapidly, being higher than rated reset temperature and keeping the circuit in the off state. When the general power is off and temperature decreases to the reset temperature of bimetallic strip, the strip recovers rapidly and contact closes, providing a safer and more reliable protection on circuits.
