Independent from temperature because of lowest TCR-values
Extremely good long-term stability, thus the energy meters do not require any recalibration
Permanent current up to 100 A (0.3 mOhm)
Qualified for 20 A-, 40 A-, 60 A- and 80 A-energy-meters
Massive copper terminals
Very high reproducibility of R-value and TCR
Mounting: Screwed on terminals of kWh-meter
