Review: Fits 2005 Mercedes S500 - Fit my 2005 S500. My dad connected a jumper back backwards and blew this fuse. It's under the front passenger carpet and fixed my issue perfectly
Review: Well Designed Fuses For a Reasonable Price - I have degrees and certifications in electronics, so I'm a little fussy about electrical safety and functionality, I really like these fuses because of tab connections, and for visible indication of blown fuse. With most of the consumer-grade high-current low-voltage fuses, the weakest part of the system is the fuse holder. Usually they are made of cheap plastic, often times with undersized wire, and often times do not make a reliable low-resistance connection to the fuse. All of these things add up to a risk of over-heating, and plastic melting, or worse. The tabs on these fuses make for reliable connections, which is what you want, especially if there are fathoms of cold water below your boat. I recently rebuilt the DC power distribution system in our older camp trailer that we inherited. The factory installed fuses were a mess. They were hard to access, hard to tell if they were blown, and hard to remove/replace. I took them all out and replaced them all with these Blue Sea fuses. Because the factory fuse blocks for these Blue Sea fuses are kind of expensive and don’t have hold enough fuses for my need, and because I enjoy making my own stuff that is better than stuff made in a Chinese factory, I made my own fuse block, which was fairly easy because the tabs on these fuses allow them to be screwed securely to an aluminum buss-bar. My fuse block is a collection of 1/2" thick aluminum blocks that are drilled and tapped for 10-24 screws for the tabs on these fuses, and for ring terminals on the ends of interconnection wires. The aluminum blocks and the buss bar are mounted on a 3/4 inch thick oak board. I now have rock solid, low-resistance fuse connections that I'm sure will perform well for many years. I'm quite happy with these fuses. They are reasonably priced and of good quality.
