CT 250A/0.333V
- TypeSplit-core CT
- Dimensions51 × 77.2 × 42 mm (W × H × D, per CT)
Overview
The Sungrow CT 250A/0.333V (Sungrow item UE000013) is the split-core, voltage-output current transformer for the DTSU666-20 three-phase smart meter: 250 A primary to 333 mV secondary. The split core clamps around the existing phase conductor, so the installation does not have to be interrupted. A three-phase measurement needs one CT per phase; the DTSU666-20 has two CT inputs (CT1 and CT2), so a second set can, for example, measure a second inverter. Sungrow supplies the CTs for the DTSU666-20 separately; some inverters ship with them by default.
Read the full description
Installation per the Sungrow quick guide: the arrow on the CT always points to the load side, the CT on IA/IA* goes on L1, IB/IB* on L2 and IC/IC* on L3. An overly long CT cable may be cut to length. Dimensions per CT 51 × 77.2 × 42 mm (W x H x D). For smaller connections there is the CT 100A/0.333V.
