Current transformers for new systems or retrofits

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.

Flexible Rogowski coil MFC150

Rogowski coils are suitable for use in systems with limited space. They enable subsequent installation without having to cut the conductors. Thanks to the integrated amplifier in our measuring devices, they can measure a current range from mA to kA.

* The flexible MFC150 Rogowski coil can only be ordered as a set, in combination with UBN40 or UBN309.

Differential current transformer DACT series

The DACT plug-in differential current transformers are designed to record small currents. In conjunction with the UBN AM / PQ EW.Fi option, they can be used for differential and residual current monitoring of machines and systems.

characteristics

• Detection of the smallest fault currents
• Safe housing with high flame retardancy
• Tamper protection through sealable covers
• High measurement accuracy up to class 0.2S
• Maintenance free
