The holder for a Class T fuse, rated to 320 A, with an insulating cover. Read the listing carefully: this is the block, and the fuse that goes in it is a separate part whose rating comes from your inverter's charge and discharge current rather than from the block. A lithium bank can deliver thousands of amps into a short, so the fuse is the one part of a build never to leave for later.
