Frequently Asked Questions
What is the current measurement accuracy of the Micrologic 2.0A, 3.0A, 5.0A and 6.0A trip units with ammeter?
Powerpact P, R, Masterpact NW, NT
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.
