Several types of Reverse Power Relays are available including relays sensitive to reverse reactive power (kVAR). KILOVAC is the leading brand of reverse power relays.  Our rugged sealed construction provides continuous and reliable operation unaffected by shock, vibration or other severe environments. Reverse Power Relays are used for the protection of generator sets operating in parallel.

## **Notes:** 

1. Remove screw for access to the pick-up and time delay adjustments. 

2. Clockwise rotation of the pick-up adjustment will raise the reverse trip point.

4. Polarity of the voltage and the current connections must be observed for true power sensing. 

5. Interchanging connections on terminals 5 and 6, will cause the output contacts to pick-up on forward power and dropout on no power or reverse power.
