What is a Power relay?

A power relay is a type of relay used to control high-power circuits. Unlike regular relays, which control low-voltage and low-current circuits, power relays are designed to handle high voltages and currents, making them essential in industrial equipment and power control systems. When current flows through the coil, it causes the internal contacts to open or close, switching the external high-power circuit on or off. Power relays play a crucial role in switching and controlling power equipment, motors, and generators, and often include protection features to prevent overcurrent and overheating.

Application of Power relay

✅ Motor control
Power relays are used to turn motors on and off, controlling the start and stop of machinery.
✅ Generator protection
Power relays monitor generator circuits and automatically disconnect them in case of overcurrent or overheating.
✅ Power equipment management
Power relays play a key role in ensuring the safety and proper functioning of high-voltage power equipment.
