Split-Core AC Current Transformer SCT-3000

3.00″ Opening measures from 400 to 3000 Amps


SCT-3000 Series split-core current transformer AC current from 400 to 3000 Amps passing through the center conductor. Split core CTs are designed for fast and easy installation.The split core design permits non-contact current measurements through magnetic field induction without requiring that the primary wire be taken offline and disconnected for CT installation.This method permits a safer,easy and portable current measurement. An internal precision burden resistor across the secondary winding of the CT provides a safe low voltage output and permits safe opening of the secondary
