Frequency Sensitive Relays
Function:
WILMAR™ Protective Relays – 20-000 Series
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).
