Safety isolating transformer
ACT 25
Characteristics
Benefits
› Integrated short-circuit and overload protection thanks to temperature fuse in the input and fuse in the output (ACT 10 only temperature fuse)
› Permanent corrosion protection, high insulation value and maximum electrical reliability thanks to XtraDenseFill resin encapsulation
› Robust plastic enclosure for rail mounting, e.g. in consumer units or meter mounting boards
