Strong Points
Function
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.

Advantages
Smart sensors
- RJ12 concept for a quick and reliable connection to the power meter.
- Color-coded RJ12 cables provides easy phase identification to prevent phase inversions.
- Automatic detection of current sensor type and rating.
- Low-voltage mV output - No shorting blocks are needed, TR sensors can be disconnected safely under load.
Accurate
- Unique PreciSense technology guaranteeing system accuracy according to IEC 61557-12 standard.
- Class 1 system accuracy (Power Meter + TR current sensor) from 2% to 120% of rated current.
Smart
Any wiring mishap, whether it’s a phase inversion, a wrong orientation or a configuration error can be corrected via software. Save time, effort and resources, avoiding the hassle of reworking physical wiring on current sensors.
