Increase the stability and reliability of your X10 installation by blocking out stray X10 signals from outside your home.
The X10 PRO 3-phase 250A Signal Blocking Coupler is designed to sense and cancel out X10 signals from crossing from one household to another via the AC wiring.
The coupler/blocker is installed outside the home between the meter and the breaker panel, on the Copper Neutral wire to sense and neutralize any X10 signals in the power feed before entering the house.
Unique features of the design include its ability to efficiently couple X10 signals between phases, the elimination of any direct connections to the power company-side wiring and the elimination of heavy current carrying inductors, resulting in a very compact design.
The unit may be used in single, dual or three phase installations.
For best results a PZZ01 should be installed at both homes experiencing the signal crossings.
