Thank you jea48 for the information on the what, why and how of fuse ratings. That helps me and I am sure others make a more informed decision. I have aftermarket fuses with the called for manufacturer rating. But I have thought if I have a problem that I may go up a notch. Now I know more about what I would be doing. Thanks
Audio Horizons fuses.... won’t buy them again...
I’ve bought 5 Audio Horizons Platinum fuses a couple of months ago, for my amps, speakers and DAC.
Three days ago, coincidentially, the 5A fuses on my mono amps (Rogue Apollos), blew at the same time on start up. Replaced them with the OEM fuses, and everything works again.
I have a very good electrical installation, with independent lines for each amp, a no surges or anything strange occurred. My speakers, Evolution Acoustics MM3s are always ON, and nothing happened to the fuses on them.
I emailed Joseph Chow inmediately and his response was to send the fuses back to him (at my cost, I live in Ecuador...), to repair them for $70/each, plus shipping.
I have paid $138 for each fuse in October, and no warranty?... what a shame!!!
Won’t buy these fuses again, NEVER!!!

Hmmm.Don't do it, the one who said that has no idea on safety or of mains or ac theory, and his advice is about as useful as ***'s on a bull. Or if your being facetious with your question, I'm with you 100%. Cheers George. |
twoleftearsIn the event of an overload condition it could be even more than double before the fuse blows. electrical characteristicshttp://download.siliconexpert.com/pdfs/2017/7/16/3/4/59/187/ech_/manual/505268968020198product-datas... For a slo-blo fuse, 1/4 amp, it could be overloaded 135% up to 60 minutes maximum before it blows. 0.25 X 135% = 0.34 amps. 0.25 amp overload condition of 200% for up to 120 seconds maximum. 0.25 X 200% = 0.5 amp Replacing a 1/4 amp with a 1/2 fuse. 1/2 amp fuse. 1/2 amp, it could be overloaded 135% up to 60 minutes max before it blows. 0.5 X 135% = 0.68 amps 0.5 amp overload condition of 200% for up to 120 seconds maximum. 0.5 X 200% = 1 amp.
