TR split-core current sensors are used with DIRIS Digiware I, DIRIS A, or DIRIS B Power Monitoring Devices to measure currents from 25 to 600 A, with the same guaranteed accuracy. The quick RJ12 connection, and the integrated intelligence prevent, any wiring or configuration errors.
TR split-core sensors are placed around the live conductors without disrupting the wiring and the supply, highly convenient for retrofit applications.
