Measurement and Communication

In addition to a complete range of current transformers, EFEN offers various special-purpose transformers for the ideal integration into smart distribution systems. In addition to this, the current transformer range is complemented by monitoring functions for power distribution components.

Low-Voltage Current Transformers

Comprehensive portfolio of windowtype current transformers, tube-type current transformers, wound-primary current transformers, summation current transformers and current transformer blocks for E3 vertical design NH Fuse-Switches complement EFEN's comprehensive range for special applications.


Integrated solutions by EFEN for remote signaling of the operating status of fuse-links for NH fuse-switches of vertical and horizontal design.

Metering devices

In addition to power metering, harmonics analysis and visualization, the multi-measurement devices are ment to save measured data. These are transmitted to superordinate power management systems via optional interface modules.
