The Littelfuse 80V Bolt-Down ZCASE® SMZ Series Stud-Mount
Fuse Holder reduces the need for wiring and parts by allowing
ZCASE® single high-current fuses to be directly installed on
an alternator, battery switch, or electrical relay. Thanks to an
insulated M8 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 M8 nut. There’s
no need to buy a specialized nylon nut.
