Instantaneous currents The instantaneous currents, available in the Measurements pages, are real time measurements of the
phase and earth fault currents expressed in root mean square value; the monitor time and performance
depend on the rated current defined by the Rating plug (In):
Monitor time Normal operating Accuracy of value
Measurement
(min-max) range read (1)
Phase currents (4) 0,004 ÷ 64 In 0,2 ÷ 1,2 In 1% (3)
Internal earth fault current (2) 0,08 ÷ 64 In 0,2 ÷ 1,2 In 2 % (3)

(1) the accuracies refer to normal operating ranges, as established by IEC 61557-12
(2) available with LSIG versions
(3) accuracies based on Ekip Touch and Ekip Touch Measuring without Class 1 Power & Energy
Metering package; if the Class 1 Power & Energy Metering package is present and for all other trip
unit models, check the indicated performance values from page 107
(4) the higher phase currents are also available in the Histograms, Measuring instruments and
Measurement summary pages
