Description

The Littelfuse 32V Bolt-Down ZCASE? SMZ Series StudMount 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 insulted 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.

The SMZ Series fuse holder is available with an M6, M8,

or M10 mounting hole to meet the requirements of various

applications. 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.
