The 15A Power Relay is an essential electrical component used to control high-power electrical systems via low-voltage signals. It functions as an automated switch that connects or disconnects circuits based on external control, making it invaluable in various industries, from home appliances to industrial automation. In this article, we will delve into what a 15A power relay is, its components, how it works, and the applications where it plays a crucial role.

What is a 15A Power Relay? A 15A power relay is a type of electromagnetic switch designed to control circuits carrying a maximum current of 15 amperes. The relay operates by using a low-voltage electrical signal to activate an electromagnetic coil inside the relay, which then physically moves contacts to complete or break the circuit. This allows a small control current to regulate a larger power circuit, thus isolating the control system from the potentially high voltage and current of the power circuit. Key Features of the 15A Power Relay Current Rating： The most notable feature of the 15A power relay is its current rating, which refers to its capacity to safely handle up to 15 amperes of electrical current. This rating is critical because it ensures the relay will function correctly without overheating or sustaining damage during operation.
