0.1, 0.2, 0.5, 1, 3 are Accuracy class
They are used for metering purposes
5P10, 5P15, 5P20 are used for metering and protection purposes
5 indicates Composite error in % and 'P' for protection and 10 means accuracy limit factor...
i.e the CT will have 5% error if the current under measurement is 10 times the normal value
