Make sure you get the right size fuse block
Great product. Used to protect batteries in a off grid solar system. Most lithium ion batteries can generate enough short circuit current that they can not only blow other fuses, but can also create an arc that will not extinguish (like a welder)… Class T fuses can handle this. 200amp and smaller class t fuses are slightly shorter than 225 amp and up class T fuses, so be sure to get the right size fuse holders for your particular application. Blue Sea website has a good online catalog where you can insure your fuses match the holder.

Returned
Had to return it. It would not fit the fuse holder made by Blue Sea. The holes were 1/16 smaller

FIRE HAZARD coating on bars creates impedence.
At 160 deg F I shut down inverter. Sanded bars with 400 grit and reinstalled. Now down to 90F. Check your torque and check for this coating.

Hope I never get to test it
Top of the line class T fuse, which is what you expect from Blue Seas. Pricey for sure so you don't want to be blowing a lot of these. This is to protect a lifepo4 280 ah battery in my sailboat. When you can't pull over to the side of the road when things go bad you want the best protection money can buy. I think this is it.
