According to IEC 60185 and DIN VDE 0414-1 current transformers measuring core rated output is specified as:

Classes:

0.1 – 0.2 – 0.5 – 1: valid in the range of 25 % and 100 % of the rated burden.

0.2 s and 0.5 s: For special applications (electrical meters that measure correctly between 50 mA and 6 A, i.e. between 1% and 120% of the rated current of 5A, e.g. for tariff measuring of active and reactive energy)

3 – 5: valid in the range 50% to 100% of the rated burden
