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.

Options
P - Transient Protection
A - Two Normally Open Contacts
B - Two Normally Closed Contacts
H - 125VDC, 3A Contacts
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
