Voltage Protection

NOTICE
Hazard of equipment damage
Setting undervoltage protection (Vmin) below 80% or voltage unbalance (Vunbal) above 20% can cause the trip unit to not perform as expected.
Failure to follow these instructions can result in equipment damage.

Voltage protection pickup settings are phase-to-phase values.

Unbalance values are based on the true RMS values of the three-phase currents.

Undervoltage alarm drops out upon the loss of the second phase.

NOTE: Do not set undervoltage protection below 80%. Do not set Vunbal above 20%*
