SPACE-SAVING FUSE BLOCKS

Ferraz Shawmut expands its popular “SJ” series fuse
blocks to now include a 100A version in addition to
the existing 30A design. These blocks occupy up
to 25% less mounting space than standard Class J
fuse blocks. A patented built-in DIN rail adapter on
the 30A SJ block adds further design versatility. A
choice of box, screw, or pressure plate connectors
fit a wide range of stranded, solid copper, or alumi­num wire for the 30A design, while the 100A design
features a box connector. Insulators are glass-filled
polycarbonate with verified dielectric strength in
excess of 2500V. Both the 30A and 100A SJ blocks
feature a unique adder block which can be snapped
onto 1-, 2-, or 3-pole blocks to form multi-pole seg­mented blocks of as many poles as desired. All fuse
clips are spring reinforced, made of high conductiv­ity tin-plated copper.

* Fuse blocks have copper box connectors and clips and are for copper wires only. These are specifically designed with the
same coefficient of expansion as copper wire for improved heat cycling and meet or exceed OEM “no aluminum” specifications.
