ANSI/IEEE C37.90-1978
Undervoltage Models - The relay is energized at
normal voltage, N.C. contacts will open and N.O.
contacts will close. The relay will de-energize when
the voltage drops below the U/V set point.
Overvoltage Models - The relay is de-energized at
normal voltage, N.C. contacts are closed and N.O.
contacts are open. The relay will energize when the
voltage rises above the O/V set point.

Options:
Blank - Standard
A = 2 Form A Contacts
B = 2 Form B Contacts
H = 125 VDC Contacts
P = Transient Protection
Transient Protection - All voltage relays will withstand
momentary voltage surges of twice the nominal rated
input voltage (standard).
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 screws for access to the O/V and U/V trip adjustment.
2.
Clockwise rotation of the adjustment potentiometer will raise the voltage trip point.
3.
The adjustments are by means of a single turn potentiometer. Use a small screwdriver and
do not force beyond the limit stops.
