The output contacts of frequency relays are ener-
gized when the frequency exceeds the adjustable
set point.
Overfrequency and underfrequency re-
lays are available in 50, 60 and 400Hz. Combination
over/underfrequency “band pass” relays are also
available.
These are energized at rated frequency
and
de-energized
during
overfrequency
or
underfrequency conditions.
Frequency Differential
relays are energized above the preset frequency.
The pick-up and drop-out frequency settings are
independently adjustable.
Operation:
The relay will energize at normal frequency; The
normally closed contacts will open and the normally
open contacts will close. The relay will drop-out after
time delay at overfrequency or underfrequency.

PART NUMBER SELECTION
Notes:
1.
Remove black screws for access to the frequency and the time adjustments.
2.
Clockwise rotation of the frequency potentiometer will raise the frequency trip point.
3.
Clockwise rotation of the time adjustment, option "T" will increase the drop-out time delay.

Time Delay
Standard Time Delay
A minimum, fixed inverse time delay is incorporated in
all frequency relays to prevent nuisance tripping and is
represented by the typical curves shown below.
Adjustable Time Delay
If additional time delay is required, a suffix "T" must be
added to the part number. This allows the minimum
fixed time delay to be field-adjustable up to 20 seconds
