ANSI/IEEE C37.90-1978
Voltage sensitive relays are available for both AC
and DC applications for overvoltage and undervoltage
protection.
Combination over/undervoltage relays
provide band-pass capabilities. AC relays are either
single or three-phase type. Three phase relays are
designed to sense the average of the three phases.
Voltage trip points are screwdriver adjustable, and
operation is time-delayed so that momentary volt-
age transients will not cause nuisance tripping.
Operation:
The relay will energize at normal voltage condition.
The normally closed contact (Form B) will open and
the normally open (Form A) will close. The relay will
de-energize after time delay when over or undervoltage
condition is reached.

Options:
Blank - Standard
A = 2 Form A Contacts
B = 2 Form B Contacts
H = 125 VDC Contacts
P = Transient Protection
Option "H" provides for contacts rating of 3 amps @
125VDC.
Option "P" provides additional transient protection which
complies with the requirements of ANSI/IEEE C37.90-
1978
Consult factory for additional models.
Notes:
1. Remove black screw for access to the voltage trip and time delay adjustment potentiometer.
2. Clockwise rotation of the voltage adjustment potentiometer will raise the voltage trip point.
3. Clockwise rotation of the time adjustment potentiometer will increase the drop-out time delay.
