®
fuse block, for 5 x 20mm size fuses, is a low
profile design that is available with a choice of solder type terminals,
NEMA style QC terminals, or PC board mountable terminals. Each of
these designs has tin-plated brass terminals. A unique design feature
provides self-alignment of the clips to the fuse caps. This feature, plus a
one-piece clip/terminal design, assures low contact resistance. An anti-
rotation feature is also available on the solder and QC terminal designs.
