The XH-SCT-S21 Clamp on current sensor senses AC current from 50 to 300 Amps passing through the center conductor. 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.
