• This is a *Lot of 3* Siemens/Furnas H5 melting alloy heaters.
• These are new old stock from my inventory of about 180 "H" heaters, now obsolete.
• I have two more listings of this size H5 heater. See 510B: H5-Lot of 6 and 510C: H5-One piece.
• Properly sizing these heaters requires several parameters.
• I have included a REALLY OLD chart in the photos that will provide an estimated guideline for amp ratings.
