Reverse Power Relays

Function:

• ANSI/IEEE C37.90-1978

• UL file No. E58048

WILMAR™ Protective Relays – 700 Series w/ Adjustable Time Delay

• 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.

120 V, Single Phase, L-N

Mounting:

Trip Adjustment ............................... Screwdriver adjustable 4% to 20% (of the 5 amp rating)

Time Delay Adjustment .................... 0.5 to 20 seconds, screwdriver adjustable

Output Contacts ............................... One set N.O., one set N.C.

Contact Ratings ................................ 5 amp resistive at 120 AC or 28 Vdc

Power Consumption ........................ Voltage circuit: 2 VA max.

Current circuit: 4 VA max.

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.

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.

7 = Reverse Inductive, 60 Hz

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.
