The Single ZCASE is a Minimal Footprint Bolt Down Fuse with a wide rating range up to
600A in the same packaging size. The Time Current characteristic is similar to the well known
MEGA Design and can used as full wire protection until 250A. Higher ratings mostly used for
typically Starter Fuse application as a protector fuse. The fuse design is optimized for a one
bolt connection M6 (40A - 250A) or M8 (300A - 600A) and can used directly on a battery post
or busbar connection. Littelfuse is offering a complete solution for the necessary stud and
different busbar connections including some battery clamps.
