What is the current measurement accuracy of the Micrologic 2.0A, 3.0A, 5.0A and 6.0A trip units with ammeter?
Issue: What is the current measurement accuracy of the Micrologic 2.0A, 3.0A, 5.0A and 6.0A trip units with ammeter?
Product Line: Powerpact P, R, Masterpact NW, NT
Environment: Distribution Equipment
Resolution: They provide continuous current measurements from 0.2 to 20 In and are accurate to within 1.5% (including the sensors).
Below 0.05 In, measurements are not significant. Between 0.05 and 0.2 In, accuracy is to within 0.5% In + 1.5% of the reading.
The optional external power supply makes it possible to display currents < 20 % In.
A digital LCD screen continuously displays the most heavily loaded phase (Imax) or
displays the I1, I2, I3, IN, Ig, IΔn, stored-current (maximeter) and setting values by
successively pressing the navigation button.
Micrologic A control units measure the true rms value of currents.
