This is a surge protector.
Delay to supply voltage for surge protector by scr.
This design is not great it s slow to act depending on a relay it will take many ms to switch off at current max relay current and a 250v mov in 120v installation won t help much either.
I want to add surge protection to all of my 15a sockets in my house.
A wiring diagram is a simplified traditional photographic representation of an electrical circuit.

Power source that when connected to an external circuit and now will turn to a current surge power supply is a high voltage surges external circuit therefore damage which can solve this problem with the delay to a power source when supply switches delay circuit to work the delay occurred during the current surge then connected to a power.
A word of caution.
The circuit once built and installed in your house will assure a total safety to the various connected appliances from all possible sudden voltage triggers.
A simple circuit idea of a mains surge protector unit has been explained in this article.
As we all know sudden mains domestic voltage fluctuations are quite inevitable and can induce serious harm to our household electrical appliances.
