Reverse Power Relays
WILMARProtective Relays 700 Series w/ Adjustable Time Delay
TERMINAL STRIPS
#6 - 32 SCREWS
Function: 32
ANSI/IEEE C37.90-1978
UL file No. E58048
CSA file No. LR61158
Several types of Reverse Power Relays are available
including relays sensitive to reverse reactive power
(KVAR). WILMAR is the leading brand of reverse power
relays. Our rugged sealed construction provides con-
tinuous 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.

Mounting:
X = Flange
Blank - Stud
Notes:
Options:
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.
7 = Reverse Inductive, 60 Hz
3. Clockwise rotation of the time adjustment will increase the time delay.
4. Polarity of the voltage and the current connections must be observed for true power sensing.
Consult factory for additional models.
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.
