Light Weight Split Core Type Current Transformer 5 - 5000A Input Snap Closing / Opening
SCTK751 Series Split Core Current Transformer with 5 to 5000A input and Snap Closing/Opening Feature,Accuracy 1.0
The SCTK751 series of split core style current transformers are designed for fast and easy installation. The split core design permits non-contact current measurements through magnetic field induction without disconnecting cables circuits for CT installation. This method permits a safer, easier and portable current measurement.
