For circuits using TTL ICs the supply voltage is a great concern and a slight increase in supply from the rated 5V may damage the IC. In this circuit a crowbar scheme is used in which a triac short circuits the power supply and burns the fuse.
Using fuses alone does not solve the problem because a fuse may take several milliseconds to blow off and that’s enough time for the IC to get damaged.


The burning time of the fuse is not a concern because the power supply is already shorted by the triac and the output voltage will be zero.
Since the switching of triac takes place within few micro seconds there will be no damage to the TTL ICs or any other such voltage sensitive components in the load circuit.
