Description of Protection
Functions
Overvoltage
Range 105–140%
(5% increments).
Undervoltage
Range 60–95%
(5% increments).
Phase Unbalance
Deviation between any
two phases percentage of
nominal line voltage preset by
DIP switches. Range 5–40%
(5% increments).
Phase Reversal
Any two phases become
reversed for the selected
delay.
Voltage Phase Loss
Less than 50% of the
nominal line voltage
detected.
Current Phase Loss
Smallest phase current is
less than1/16 of the largest
phase current.
Delay
Allows a delay before an alarm
occurs. (Range 1–20 seconds
in 1 second increments.)
Note: Unit must be powered for
this to occur.
Inputs and Outputs
(4100 Model)
Three Form C relay outputs
selectable: Trip, Alarm,
kWh pulse initiator
One synch input for kW
utility demand sync
