Are you learning about the types of relays used in control and protection circuits for electrical systems? Save this list of 10 common Relays from the image above right away:

1. Electromagnetic Relay: Traditional electromagnetic relay used for control circuits.

2. Thermal Relay: Thermal overload relay protecting motor overloads.

3. Solid State Relay (SSR): Semiconductor relay with no mechanical contacts, offering a long lifespan.

4. Time Delay Relay: Relay with a time delay function.

5. Overcurrent Relay & 6. Overvoltage Relay: Relays providing overcurrent and overvoltage protection.

7. Undervoltage Relay: Relay protecting against under-voltage conditions.

8. Differential Relay: Differential relay protecting transformers or generators.

9. Earth Fault Relay: Relay providing earth fault protection.

10. Reverse Power Relay: Relay preventing reverse power flow.
