Window Size: according to the specification and number of busbars.
Rated Current Ratio: 1/3 larger than the measured primary current.
Rated Secondary Current: 5A or 1A. When the installation location of the instrument is far away from the current transformer or the loop load is large, please choose the secondary current of 1A.
Rated Burden: the measuring instrument is connected to terminals S1 and S2, and the total load of the connected circuit should not exceed the transformer’s rated load/burden.
Accuracy Class: for measurement—class 1.0, 0.5, 0.2, 0.5S, 0.2S; for protection—class 5P10, 5P20, 10P10, 10P20.
