The operating principle of the TH10 is both simple and effective.

At the heart of the protector is a Klixon® bimetal snapation disc.

When the temperature of this disc reaches its precalibrated temperature it snaps open, resulting in an open circuit.

This temperature is reached during a fault condition, caused by either an increase in ambient temperature, in increase in current flowing thru the disc, or a combination of both.

After the TH10 breaks the circuit, the system cools and the TH10 automatically resets allowing power to be restored in the circuit.
