Plug-in current transformer (E)ASK 31.3
Plug-in transformers are suitable for primary rated currents from 75 A to 750 A and for use as measuring transformers of different currents. Can be used for round cables and busbars. Are often permanently installed in electrical systems. For installation, the respective conductor must be disconnected and routed through the current transformer. Approved as EASK for billing measurements.
