• Mounts directly to a M10 or M8 stud
• Uses high amp ZCASE fuses, (M8) available 40-600A
• Tin plate coating on the busbar ensures
corrosion resistance
• Fusing directly on the alternator, battery switch or relay
reduces the number of wire connections and parts counts
which helps to lower assembly times.
• ZCASE fuse holder uses an isolated stud so any standard
M8 nut can be used (included), simplifying replacement
and repair

Description
The SMZ stud mount fuse holder allows you to mount fusing
directly to a M8 or M10 stud on applications such as batteries,
alternators, battery switches or electrical relays. The SMZ
series accepts the Littelfuse proprietary ZCASE fuse that is
available in 40-600A ratings with similar characteristics to the
MEGA® fuse. The SMZ stud mount fuse holder is ideal for
stacking to create a 2 and 3 circuit version (see image above)
and is secured to a stud using a standard M8 or M10 nut (sold
separately). The insulated bolt on the busbar eliminates the
traditional need for nylon nuts used on legacy CF8 fuses. The
ZCASE fuses can be assembled using a standard M8 flange
nut included with each part number.
Applications
• Mounts directly to a stud style battery terminal or
alternator stud
• Mounts directly to a battery switch or relay stud
• Consolidate multiple fuseholders and reduce wiring
• High amperage starter circuit protection
Recommended Fuse
The SMZ stud mount fuse holder features a compact design
which saves space and eliminates the need to wire in a
separate fuse holder or power distribution module. Additional
circuits are added to the battery circuit directly on top of the
ZCASE fuse with wired ring terminals. The fuse holder is
available in 4 configurations, each with a red protective cover
designed to reduce the risk of accidental contact with the
fuse or battery terminal.
