Re: [PSES] Very high temperature thermal fuse / snap switch

2022-01-06 Thread Douglas E Powell 
Charlie,

It seems to me that you will eventually be limited by the metallurgy of the
fusible element. Most fuses are made of NiCr wire or  other  alloy with
nickel content. NiCr does have a melting point near 1400 C, but I've never
run across a thermal fuse that goes beyond 200-250 C. I suppose you could
try constructing your own, but there are several problems. It would be
non-certified, and very difficult to control the melting temperature with
any precision, since most thermal fuses open based on the combination of
current and temperature.  If you decide to try this,
https://www.goodfellow.com/ is a possible source for exotic wire types, and
they have a nice search tool as well.

[PSES] Very high temperature thermal fuse / snap switch

2022-01-06 Thread Charlie Blackham 
Client is looking for a thermal fuse or similar that would operate at around 
800 C - does anyone know of such a component?

Best regards
Charlie
