Fronius CTA1005A Current Transformer 100A/5A Split Core Smart Meter (NEW In Box)

The Fronius CTA1005A is a split-core current transformer with a 100 A to 5 A ratio, supplied as an accessory for the Fronius Smart Meter. It clips around an existing conductor without the need to disconnect the cable, stepping the primary current down to a 5 A secondary signal that the meter measures.

This is a genuine Fronius part carrying the order code 41,0010,0089 and marked ECS24100 on the housing. It is a Class 1 accuracy device rated for 50 to 60 Hz operation, fitted with red and black flying leads for connection to the meter's current inputs.
