Allnet 23651 ALLL168X Phase Coupler 3-Phase 1-40 MHz 400V AC Component

Eichhoff phase coupler in a 3-phase version with LX "coupling with other networks". The phase coupler helps powerline signals to transfer from one phase to the other. Especially if a 3-phase line (e.g. stove connection) was not laid in an old building, the "cross-talk" of the powerline signals sometimes does not occur to a sufficient degree.
