ZCASE Single MEGA/Starter Fuse

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.

Time-Current Characteristic Curves

All ZCASE Starters T/C curves were

performed on the left or right side of

the metal bar as shown in pictures

above. A 50mm² Cu wire was mounted

at the mid hole (M8) of the metal bar

as current feed.
