Description

The metric Omni-Blok

fuse block, for

5×20mm 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-one-piece

clip/terminal design, assures low contact

resistance. An anti rotation feature is also

available on the solder and QC terminal

designs.
