Value
Data Type Attribute Description
USINT Percent phase imbalance
USINT Percent thermal capacity
USINT Trip class setting 5 to 30
UINT The present FLA setting. The potentiometer selects this value. The value is scaled by
the multiplier.
UINT Average of the three phase currents, scaled by the current multiplier
UINT Actual motor phase current L1, scaled by the current multiplier
UINT Actual motor phase current L2, scaled by the current multiplier
UINT Actual motor phase current L3, scaled by the current multiplier
UINT RMS ground current, scaled by the current multiplier
UINT This is the max FLA setting possible in this device. The value is scaled by the current
multiplier.
UINT This is the min FLA setting possible in this device. The value is scaled by the current
multiplier.
UINT This value indicates the multiplier applied to the current values. For example: If the
multiplier is 10 then all currents are read out in deci-amps. 1A => 10; Divide the given
current value (attribute 140, 141, 142, and so on) by the value in this location to
convert to amps.
UINT Presents the average current as a percent of the FLA setting.
USINT Percent of ground fault measured. GF% = GFC / ([0.5]*FLA)
