Hey I have this thermal cutoff fuse and I want to find a replacement.

But if I can find a data sheet or spec sheet with your help that’s all I need to find a compatible fuse to use.

The fuse has this printed:

A-YX01
E478338
ru 94V-0
HRS2057-C
16.05.08

Thanks in advance

To me . . . . . that just looks like a blown fusible link that was etched on the copper foil and is dependent / and / needing to be replicated of the same dimensions and using the same oz weight of foil.
Definition of detail, precludes my making out the associated background clutter, but is being automotive related ?

As per Edd above - you could fit a standard fuse of the appropriate rating and, potentially, a proper holder for the fuse too (allows easy replacement). Tell us more about its purpose, the equipment etc. Looks to be around 20A or 25A to me.

It’s for this but I can’t find any details on it or data sheet for it, but both of you are right and yes as Kelly said above im trying to find a compatible fuse with the holder so if it blows or I need to replace it then it’s a lot easier.

Kinda think there's some exaggeration in the specs..... either way, the 'fuse' you're referring to certainly isn't rated at anything over 30A as the WIRE it's connected to seems to be 14awg (?) therefore 30A is the 'recommended limit.

The only reasonable fuse holder would be what's called a 'blade fuse holder' - standard stuff for vehicle use and readily available, as are the fuses. Start with a 25A fuse....

That’s exactly what I wanted to use just wasn’t sure if I could, the other thing I wasn’t to sure about is if I should use a standard one or a small fuse holder.

Hi There, I have the same issue, trying to find replacement of this fuse, did you end up fixing yours with a blade fuse?
