Application Data
Phase Loss:
Unit trips on loss of any Phase A, B or C.
Phase Reversal:
Unit trips if rotation (sequence) of the three phases is anything
other than A-B-C.
Undervoltage:
Adjustable from 80-95% of nominal voltage. Unit trips when
the average of all three lines is less than the adjusted set point
for a period longer than the adjustable time delay drop-out.
Overvoltage:
Fixed at 110% of nominal voltage. Unit trips when the average
of all three lines is greater than the fixed set point for a period
longer than the time delay drop-out.
Phase Unbalance:
Adjustable from 2 - 10% unbalance. Unit trips when any one of
the three lines deviates from the average of all three lines by
more than the adjusted set point . There is also a “Disable”
setting adjustment that will turn off the Phase Unbalance
Protection if nuisance tripping is a problem.

Hysteresis: 2 - 3%
Load (burden): Less than 3VA
Temperature: -28
Mounting:
Does not require a socket. Can either be mounted directly on
35mm DIN track with no additional parts or to a back-panel
with two screws.

Reset:
As standard, reset is automatic upon correction of fault.
When a momentary-contact N.C. switch is wired across the
Manual Reset terminals (5 & 6), the unit switches to manual
reset mode and remote manual reset is available.
