BMZ SERIES BATTERY POST MOUNT ZCASE® FUSE HOLDER
275A • 32V DC • 2-way or 3-way • ZCASE®
Description
The BMZ battery post mount fuse holder allows you to mount
fusing directly to a post style battery terminal. The BMZ series
accepts the Littelfuse proprietary ZCASE fuse that is available
in 80-600A ratings with similar characteristics to the MEGA®
fuse. The BMZ post mount fuse holder mounts directly to the
battery without any need for additional mounting hardware
and is available in 2 or 3-pole versions (see image above). 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. Fuse mounting
nuts are included with the boxed kits but need to be sourced
separately when ordering individual components.
The BMZ post 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 directly on top of the ZCASE
fuse with wired ring terminals. The fuse holder is available in
individual component part numbers and in a complete boxed
kit.
