> The relays which we use in the Top Ten Devices boxes are 10 
> amp,
> sealed power relays.  They are very small and have very low
> inductance.  The contacts are connected to the base pins with
> wide conductors.  I have run many power tests on these relays
> and the pc boards they are mounted on with temperature monitors
> and they will take full amateur power (+) to over 30 MHz.  We
> rate our boxes conservatively at 1.5 KW.  The part number is
> JW1FSN-DC12V.  They come with several different brand names on
> them.  Similar relays are being used by other manufactures of
> amateur boxes and they rate them variously at 3 KW and 5 KW.
