Understanding Relay Current： Key Considerations and Applications

Relays are essential components in the world of electrical engineering, used for controlling circuits with low-power signals to switch high-power devices. One of the fundamental aspects of relay operation is the relay current, which refers to the electrical current passing through the relay’s contacts during the switching process. Understanding relay current is crucial for the proper selection and application of relays in various electrical systems. This article delves into the concept of relay current, its significance, and the key factors to consider when dealing with relays in practical applications.
