Modular Fuse Blocks

The Modular semiconductor fuse blocks feature modular mounting that offers greater flexibility in adjusting to various fuse lengths. Both stud type and integral box connector versions are offered to allow for user preference of wire terminations. The integral box connector versions also provide for greater heat dissipation. All modular blocks are supplied in pairs but need to be ordered as two items to suit one fuse. Mounting hardware is supplied with the blocks.
