Precision four-terminal shunts for current measurement in traction circuits and onboard energy meters, with a 30–60 mV voltage drop and accuracy class 0.2 or 0.5 according to EN 50463. Thermal parameters and resistance stability over a wide temperature range determine the accuracy of the entire measurement chain, which is why the shunts are selected together with a P41000 or P51000 transmitter as a matched measurement system. EN 50463 certification confirms suitability for onboard rolling-stock energy metering.
