hi,
The are 'inline' interference suppressors, for two and three core cables.
They are wound is such a 'sense' as any common mode interference is attenuated.

I understand how 126 works (3 separate 2line interference suppressors) but the 3line is evading me ... can you give me a simple 3 line example schematic with some base explanation ..

the way I understood it, 2line one can be, for example, placed on power line so the inside of the circuit will be isolated from the interferences that exist on the main power input... but .. 3line .. damn, I have no idea and the "symbol" for the 3line one does not tell me much
