Product Description:
The Frer TAC033 is a high-precision measurement current transformer designed for electrical distribution systems, metering, and energy management panels. Made in Italy, this transformer steps down primary alternating current to a $1\text{ A}$ secondary output while maintaining high accuracy compliant with IEC 60044-1 standards.
Multi-Class Accuracy Ratings: Offers Class 0.5, Class 1, and Class 3 accuracy options depending on the burden load applied.
Primary / Secondary Ratio: 100A primary to 1A secondary current transformation rating.
Instrument Security Factor (FS $\le$ 5): Protects connected secondary measuring instruments against system overcurrent faults.
Dual Cable Aperture: Designed to accommodate up to $2 \times \text{Cables}$ through the core.
Compliance Standards: Built to IEC 60044-1 international standards and CE marked.
