3MP SELF

3MP Self Hold

The operating principle of the 3MP Self Fold 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 3MP Self Hold breaks the circuit, the system cools and the 3MP Self Hold automatically resets allowing power to be restored in the circuit.
