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.
- Accepts high-current ZCASE® single bolt-down M8-size or M10-size fuses, depending on the model (fuses sold separately)
- Available mounting hole sizes include M6, M8, and M10
- Up to 3 SMZ Series fuse holders can be stacked to protect multiple circuits
- Space-saving design eliminates the need to wire in a separate fuse holder or power distribution module (PDM)
- Tin-plated copper busbar offers corrosion resistance
- Red UL 94 V-0–rated covers prevent accidental contact. One version covers just the fuse only, and the other covers the fuse and mounting stud.
- Total continuous current should not exceed 400 A per holder
