Hi All,

Jim sent me two fuses he had.  They are PT fuses rated at 4800V 2 
amps.  The current break rating is 50,000 amps!!!  That is 200+ MVA!!

Since one was blown, I sawed it open:

Basically, just a fiberglass tube filled with sand.  A very thin wire was 
wrapped around the center fiberglass board at about 2 turns per inch.  Very 
simple really.

Thanks Jim ;-)  Very interesting to see how it is really done!

Cheers,
