CLASS J FUSE BLOCKS
Ferraz Shawmut Class J Fuse Blocks accommodate
all Class J fuses. A choice of screw, pressure plate,
box and special order stud connectors fit a wide
range of stranded or solid copper or aluminum
wire. Insulators are either molded glass-filled
polycarbonate (GFPC) or phenolic with verified
dielectric strength in excess of 2500V. 30 and 60A
fuse 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 made of high conductivity
tin-plated copper, with a choice of spring reinforced
or non-spring reinforced clips in 30A and 60A.
Clips 100A and above are spring reinforced.
