The ZCASE® SMZ Series Bolt-Down Stud-Mount Fuse Holder reduces the need for wiring and parts by allowing ZCASE® high-current fuses to be directly installed on an alternator, battery switch, or electrical relay. Thanks to an insulated M8 or M10 stud on the busbar, the compatible fuse (sold separately) and output cable with a ring terminal (not included) can be assembled using the included standard nut.The SMZ Series M8 ZCASE® fuse holder is available with an M6, M8, or M10 mounting hole to meet the requirements of various applications, and the M10 ZCASE® fuse holder features an M10 mounting hole. Various configurations, including with a protective cover for the fuse only, with a protective cover for the fuse and mounting stud, and without a cover, are available.
