Current transformer TGH / TGK

The multi-range current transformer with 5 VA nominal burden and accuracy class 0,5 S is qualified for electronic metering. Due to the extendet measuring range, the whole range from 100 to 1500 A can be covered by 3 courant transformers with the ratios of 300/5, 800/5 and 1500/5 A. These transformers are applied as bus-bar-types and plug-in CT’s as well.
