Meter Cabinet / Enclosure Current Transformers
High Accuracy, Extended Range
High-accuracy, extended-range transformers exceed the IEEE 0.15S accuracy standard, delivering 0.15% metering accuracy from 1% of rated current through rating factor.
Key Features:
- High rating factors, superior temperature performance, and top-tier metering accuracy
- Broad portfolio capable of replacing any major legacy brands
- Solid dielectric construction for extended outdoor life
Description
600V metering current transformers are used in a wide range of commercial and industrial metering installations where revenue-class accuracy is required for billing, and is specifically designed for meter cabinet enclosures.
Construction:
The core is constructed from wound layers of high accuracy, low loss electrical grade steel. The core is evenly wound with enamel coated copper wire to ensure against potential short circuits. The core and coil assembly is encapsulated in polyurethane specifically engineered for premium dielectric, mechanical and thermal properties for indoor and outdoor applications.
