In accordance with IEC62053-21 standards, the energy meter must be safeguarded from
external magnetic fields to prevent potential tampering. The TOPRO shielded Current transformer T-02
utilizes a custom metal shield (Material: DT4E) to protect against external magnetic fields,
offering the option of DC immunity.
Product Features
1. Suitable for electronic electricity meters, both single phase and three phase energy meters.
2. Utilizes high-quality amorphous alloy and nanocrystalline core for excellent linearity and precision.
3. CT case made from flame retardant PBT materials, providing strong mechanical and electrical properties.
4. Epoxy resin encapsulation ensures high insulation capabilities.
5. DC immune current transformers (DCT) can be used in electricity meters, meeting IEC62053-21 and ANSI C12.20
standards.
6. Metal shield included to protect CT from external magnetic fields up to 300mT.
7. RoHS compliant and CE certified.
