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

Resolution:
They provide continuous current measurements from 0.2 to 20x In and are accurate to within 1.5% (including the sensors).
Below 0.05x In, measurements are not significant. Between 0.05-0.2x 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.
