HTRS Series

A current sensor with a split core structure, allows to install the measurement system on an existing power cable, and this without disconnection and reconnection process.

New sensor for trackside market

Compact Split-Core: HTRS

HTRS

The unique technology used by LEM, remove the drawbacks of the inaccuracy of the split-core sensors, coming from the imperfect contact between the 2 core halves.


HTRS range covers from 1 A to 100 A (max) primary current sensing.
Nominal current 10 – 30 – 50 A (IPmax = 2 times nominal)


The new HTRS can be mounted using screws or the add-on Din-Rail connector.
Din rail allows different orientation of the sensor, with a 90° steps.
