The Series 349
Under/Over Voltage Sensing
Relay incorporates a Series 219 relay and an
Electronic Module. Pull-in Voltage is adjustable
between 85 and 135 VAC for frequencies from
50 to 400 Hz. Models available for Single and
Three Phase sensing with differential (between
pull-in and Dropout) Adjustable from 2 to 14 Volts
by external fixed or adjustable resistor. Single
Phase relays are also available with standard 3
volt fixed differential and other fixed values up to
14 volts, on special order.
