🧰 What is a Danfoss Relay?

A Danfoss relay is a small electrical device used to start and protect the compressor motor. It controls the power supply to the start and run windings of the compressor. Using the wrong relay can cause compressor overheating, failure to start, or even damage to the unit. Therefore, always use the correct relay model based on the compressor’s horsepower (HP).

How to Identify the Right Danfoss Relay

1. Check Compressor Label: Every compressor has a label with model number and HP rating.

2. Match with Chart: Use the HP size to find the correct relay number from the table above.

3. Use Genuine Parts: Always use original Danfoss relays for long life and reliable performance.

4. Avoid Universal Relays: They might work temporarily but can damage the compressor in the long run.

Conclusion

Using the correct Danfoss relay according to compressor HP ensures smooth starting, long life, and protection from overload or short circuit. Always refer to a reliable Danfoss Relay Number Chart like the one above when repairing or replacing relays in refrigeration or air-conditioning systems.
