Voltage sensitive relays are available for both AC and
DC applications for over/undervoltage protection.
Combination over/undervoltage relays provide
bandpass capabilities. AC relays are either single or
three-phase type. Three phase models are de-
signed to sense the average of the three phases or
the highest single phase. Voltage trip points are
screwdriver adjustable, and operation is time-de-
layed so that momentary voltage transients will not
cause nuisance tripping.

Transient Protection - All voltage relays will withstand
momentary voltage surges of twice the nominal rated
input voltage (standard).

Notes:
1. Remove black screw for access to the voltage trip adjustment.
Consult factory for additional models.
2. Clockwise rotation of the adjustment potentiometer will raise the voltage trip point.
