PQube User Manual 2.1

In general, the accuracy of your PQube’s current measurements are so precise (roughly ±0.1%) that
the accuracy of your current measurements will be determined almost entirely by the current
transformer that you select.
CT4 Current Module
If you don’t already have CTs, but you want to measure current, you
can use the optional CT4 module. It has the CTs already built in and
ready to use.
The CT4 comes in two models: the CT4-20A (for nominal currents up to
20 amps) and the CT4-50A (for nominal currents up to 50A). Both
versions can accept conductors up to 0.34 inches (8,6mm) in diameter.
600V, UL-recognized insulation is required.
