What is a 12V 100A Relay?

    A relay is essentially an electrically operated switch that allow a low-voltage control signal to control a high-voltage or high-current circuit. The "12V" in the name refers to the coil voltage required to activate the relay, while the "100A" denotes the maximum current the relay can handle on its switched contacts. The 12V 100A relay is typically designed to switch large current loads, such as those found in automotive, marine, and industrial systems.

    Reays operate on the principle of electromagnetism. When the control voltage (12V in this case) is applied to the relay’s coil, it generates a magnetic field that attracts a movable armature. This movement either opens or closes the switch contacts, allowing the high-current circuit to be completed or interrupted.ls    A 12V 100A relay is an essential electrical component widely used in various industrial and automotive applications. Its primary function is to control high-current circuits using low-power control signals, making it invaluable in situations where large currents need to be switched on and off efficiently. In this article, we’ll explore the working principle, applications, and benefits of the 12V 100A relay.
