Works on Polaris RZR Pro XP4 1000 Premium.
This worked perfect as a replacement fuse for our 2023 Polaris RzR Pro XP4 1000 Premium. The fuse in the center console are where the cigarette outlet is has a big fuse like this under the battery terminal Connection cable that blew. This worked perfect and was substantially more affordable than the OEM or anything I could find at local marine and off road stores in my area. Has been fully submerged under water repeatedly and still works without any issues.

I bought these after learning my prior fuses might not work well
I did some research while ensuring my van battery system was correctly setup. I initially ordered a cheaper fuses, but found out that these were so much better, and safer then a cheaper one I ordered first from Bojack. I had concerns after watching several Youtube videos about those fuses, and decided to get these ones instead. I feel so much safer having both the 300a and 100a installed on my MRFB and not the other ones. Note: Not saying I had anything personally happen with the prior fuses, but just do your own research before committing to something that will safe your life in the long run.

Important safety device on a boat
I bought a bunch of these to install on the batteries on my boat. I have a vry large house battery, using golf cart flooded batteries (Yeah, I know that LI are supposed to be better, but I would have to re-wire and re-configure a LOT of stuff). They are easy to use if you have enough room on the battery studs, or can make a stud extender. I flattened a piece of 1/2 inch copper pipe and drilled holes in it to add several of these fuses that protect the wiring coming off of the batteries. I had one pop last year, when the anchor windlass jammed, and I did not have a spare fuse on board. But very easy to bypass them in an emergency, if absolutely necessary. Recommended.
