with Noise Suppressor and Overload Protection. Circuit board with spade connectors for C Track, and with a red and brown feeder wire. One needed for each conventional track circuit. One 74046 feeder wire set should be installed in each track power circuit to protect against possible radio and television interference caused by locomotives in operation. This feeder wire set also offers effective protection against overloads and short circuits, protection that responds very quickly, even with older transformers. The protective functions remain in effect when you use the 74042 Supplemental Feeder Wire Set for additional connections to the track in the same power circuit.
To be used only on Conventional or ANALOG Layouts. Do not use on Digital Layouts.
