Surge Protector Schematic

As we all know sudden mains domestic voltage fluctuations are quite inevitable and can induce serious harm to our household electrical appliances.

Surge protector schematic.

The circuit diagram of a surge protector is shown below. 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. Surge protection circuit is the one referred by many as protector for voltage spikes in ac grid lines. These are normally installed in sensitive and vulnerable electronic equipment to prevent them from getting damaged due to these sudden unprecedented surges and voltage.

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. However it is not limited particularly in ac grid lines. 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. This circuit helps in protecting the equipment from the damage which is caused by transient surge voltages like strikes of lightning apparatus switching operations.

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. A wiring diagram is a simplified traditional photographic representation of an electrical circuit. A simple circuit idea of a mains surge protector unit has been explained in this article.

A word of caution.
