MersenA3T Fast Acting/Class T Fuse, 300VAC/160VDC, 200kA AC/50kA DC, 200 Ampere, 1-1/16" Diameter x 2-7/16" Length

well, yes it is. (i guess) *HOWEVER* it does NOT fit in my Blue Sea Systems Class-T fuse holder. the holes in this fuse are 5/16. (not 3/8 like the fuse holder) and they are too close together to fit the fuse holder. i ended up drilling them out and MAKING it fit, but don't know if that is the best/safest idea. with only hearing about "class-T" fuses within the last few months, i'm unfamiliar with them. are there different sizes?? i only ask b/c the Mersen 400A fuse i got fits JUST FINE, but these 200A ones don't.... i've aparently got more to learn. just wanted to write this for anyone else fusing a solar setup and just *ASSUMED* a class-t fuse fits in a class-t fuse holder. it doesn't. sometimes. other times it does...

These fuses are great, i use them for my 48 volt battery bank because they can handle the higher voltage.Sadly i never received my order, bad customer service

Need this fuse for my old buy reliable inverter in my solar system. These arrive quickly and work well.

Really bad quality control on the fuse I received. The two ends are clocked 4-5 degrees from each other, meaning that it wont make good contact on the fuse holder. I guess this one is going back...

Works 👍

Item for resale works as expected

Great replacement fast shipping thanks

Perfect replacement part with a much better price than others.
