• This is a *Lot of 3* Siemens/Furnas H78 melting alloy heaters. One is in the original box. The other two have no box.
• These are new old stock from my inventory of about 180 "H" heaters, now obsolete.
• I have another listing of this size H78 heater. See 537A: H78-Lot of 3.
• 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.
• If you need help selecting the size of the heater you need, message me.
