Frequency Sensitive Relays

WILMAR™ Protective Relays – 20-000 Series

Function:

81 O

The output contacts of frequency relays are ener-

gized when the frequency exceeds the adjustable set

point. Overfrequency and underfrequency relays are

available in 50, 60 and 400Hz. Combination over/

underfrequency “band pass” relays are also avail-

able. These are energized at rated frequency and de-

energized during overfrequency or underfrequency

conditions. Frequency Differential relays are ener-

gized between the preset frequencies. The pick-up

and drop-out frequency settings are independently

adjustable.

#6 - 32 STUDS

6 PLACES

Operation:

The normally open contacts close, and the normally

closed contacts open, at all frequencies above the set

point. The contacts in the connection diagram, are

shown in the de-energized position (below the trip

set point).
