Instrument current
Transformers, indoor,
Cast-Resin Insulated

On Request:
Constructions with capacitive layer
Ribs on the top for increasing creepage distance(AMS24-R,AM24-R,AMG24-R)
Ribs height 35 mm
* Change over: with multi-purpose transformers it is possible to work with several primary currents. In principle, the change over can be made from the primary as well as from the secondary side.
(Secondary tapping; for instance 800-1000/5A)
