Frequency Sensitive Relays
WILMAR™ Protective Relays – 25-000 Series
Function:
81 O/U
• ANSI/IEEE C37.90-1978
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 above the preset frequency. The pick-up and
drop-out frequency settings are independently ad-
justable.

Operation:
The normally open contacts close, and the normally
closed contacts open, at nominal frequency. The
contacts are de-energize at underfrequency,
overfrequency or no input voltage.

The contacts are shown in the de-energized position.
Remove screws for access to the underfrequency and overfrequency trip adjustments.
Clockwise rotation of the adjustment potentiometer will raise the frequency trip points.
