Note:

1. The first item of each gear below the rated current of the multi-variable ratio current transformer is designed to be 600 ampere turns, such as 50-70-100/5

The ampere turns of each gear are 600-900-1200IN.

2.0.2S,0.2 grade: 600-900IN is 20VA, and above 900IN is 25VA. 0.5 grade: 600-800IN is 25VA,900IN above is 30VA. 10P10 grade: 600IN-900IN is 30VA, above 900IN is 40VA. 10P15 grade: 600IN-900IN is 20VA, above 900IN is 30VA.

The rated output in the table only lists the first data of each specification of the polytropic ratio. 3. The difference between the two gears before and after the current transformer is less than or equal to 2 times,

Such as 100-150-200/5,300-400-500/5, etc.
