It reveals the components of the circuit as simplified shapes and the power as well as signal connections in between the tools.

This is a surge protector.
However it is not limited particularly in ac grid lines.
A word of caution.
A surge protector is an electrical device which is designed to neutralize minor electrical spikes and transients that normally keep appearing in the mains utility lines.
As we all know sudden mains domestic voltage fluctuations are quite inevitable and can induce serious harm to our household electrical appliances.
These are normally installed in sensitive and vulnerable electronic equipment to prevent them from getting damaged due to these sudden unprecedented surges and voltage.
This circuit helps in protecting the equipment from the damage which is caused by transient surge voltages like strikes of lightning apparatus switching operations.
Surge protector or surge protection device is a device that will provide surge suppression or voltage spike suppression so that sensitive devices will not get damage.
The circuit diagram of a surge protector is shown below.
A simple circuit idea of a mains surge protector unit has been explained in this article.
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.
