ORDERING INFORMATION
THREE-PHASE VOLTAGE MONITORS
258, 269
DESCRIPTION
Models 258 and 269 continuously monitor three-phase
power lines for phase loss, phase reversal, and low voltage.
Model 269 also monitors for high voltage. Models 258 and
269 do not require a neutral connection and can be used
with any Wye or Delta systems. When correct voltage and
phase rotation are applied, the internal relay will energize.
A fault condition will de-energize the relay. When the fault is
corrected, the monitor will automatically reset.
