Applications

Measurement of high primary currents, the transformer has a small secondary current output Current output which can then be connected to measuring devices, e.g. UMG 96.


If the The measuring device has to be replaced, the consumer does not have to be switched off switched off, as the measuring device is not directly connected to the supply line in the supply line. This prevents unplanned system downtimes.


Important: Operation of the current transformer in the upper third of the specified amperage.


Installation note: Observe the direction of current flow P1in P2out
