Description
The Eastron ESCT-T series of split core current transformers are designed for fast and easy installation. The split core deign permits non-contact current measurements through magnetic field induction without requiring that the primary wire be taken off line and disconnected for CT installation. This method authorized 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 authorized safe opening of the secondary circuit.
