A 220V AC relay is an essential electrical component used to control high-voltage alternating current (AC) circuits with low-voltage signals. It works as an electrically operated switch, and it plays a vital role in various applications, from household appliances to industrial automation systems. In this article, we will explore the key features of 220V AC relays, their common uses, and the safety precautions one should consider when using them.

What is a 220V AC Relay? A relay is an electromagnetic switch that allows a low-voltage control circuit to open or close a high-voltage circuit. The 220V AC relay is specifically designed to control 220-volt alternating current (AC) circuits, which are commonly used in residential and commercial power systems. The relay consists of an electromagnet (or coil), a set of contacts, and a mechanical armature. When the coil is energized, it generates a magnetic field that pulls or pushes the armature to change the position of the contacts, thus completing or breaking the circuit.
