A 15A power relay is a crucial electrical component in various devices that require switching of higher power loads. These relays, commonly used in household appliances, industrial machinery, and automotive systems, allow for the control of high-power circuits with a low-power control signal. This ability to switch large currents and voltages using small electrical impulses is fundamental to the smooth operation of many systems.
What is a 15A Power Relay? A 15A power relay is an electromagnetic switch designed to handle currents up to 15 amperes. The “15A” refers to the maximum current rating that the relay can safely handle on its contacts. This rating makes it ideal for controlling larger electrical loads such as motors, lights, and appliances in both residential and industrial settings. Relays work by utilizing an electromagnetic coil that, when energized, creates a magnetic field. This field pulls a metal armature, closing or opening the relay’s contacts, thereby completing or interrupting the circuit. When the coil is de-energized, the armature returns to its original position, allowing the relay to perform its switching function.
