Operation counters Number of mechanical and electrical operations 97

Instantaneous currents The instantaneous currents, available in the Main page and Summary 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 nominal size of the Trip unit:
Monitor time Normal operating Accuracy of value
Measurement
(min-max) range read (1)
Phase currents 0,004 ÷ 64 In 0,2 ÷ 1,2 In 1% (3)
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 101
