RedArc 40A Fuse Kit Includes:1x 40A Fuse Kit - FK40 Details:One of the most common failures the REDARC technical support team hear about�with dual battery installations is a failure of the fuse/holder. This failure can result�in the fuse and holder melting causing the connection to be lost and, therefore, no�charging of your auxiliary battery. This situation is usually diagnosed as a blown�fuse however it is more likely attributed to a poor quality fuse holder. Poor quality fuse holders often don�t make adequate contact with the fuse which�can allow dirt and dust to get in between the contact points. This causes excess�heat to be generated due to the high resistance. This excess heat can be enough�to melt the fuse and the holder. Even if the fuse holder doesn�t melt, you could be�losing valuable charge to heat dissipation. REDARC fuse kits use only the best quality fuses and fuse holders designed to fit�the cable required for the specified current and make a solid connection, giving�you peace of mind that your installation is working efficiently and safely. REDARC offers fuse kits in 40A and 60A versions designed for BCDC installations�and a 100A version designed for SBI installations.
