## Description

Recommended by most inverter manufacturers Extremely fast short-circuit response 20,000 Ampere Interrupt Capacity (AIC) for large battery banks including Lithium-ion and TPPL batteries.

Review: Quality - Replacing the lead/acid camper batteries with lithium system. This worked very well for me.
Review: 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.

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.
