  1. Rated primary current.

2. Rated secondary current: 1A/5A

3. Rated frequency:50Hz/60Hz

4. Hole diameter.

5. Precision level: 0.2, 0.5

6. Rated secondary side load

7. Enclosure material: Fire retardation PBT/Fire   retardation ABS.

RANGE

 Rated primary current: from 50A to 2000 A

 Hole diameter:   80mm-300mm

 Rated secondary side load: 2.5-10VA

TESTING AND QUALITY

All Mingrui Zero   Sequence Current Transformers are designed, rated, manufactured and tested in   strict compliance with IEC60044-1. Routine tests performed on each Zero   Sequence Current Transformer are power frequency withstand test, short time   current test, temperature rise test, verification of terminal markings and   inter-turn overvoltage test . Mingrui's internal quality system has been   developed and certified under ISO 9001 quality system

CONSTRUCTION

High insulation   flam-retardant casing with a silicon steel coil made toroidal core on which   the secondary coil wound and sealing with epoxy resin.
