Description
This low profile Omni-Blok® Fuse Block
design is available with a choice of solder
type terminals, Q.C. terminals or P.C. board
mountable terminals. The PCB design is
offered with either tin-plated brass terminals
for normal applications or tin-plated
beryllium copper terminals for use in caustic
environments. These fuse blocks feature
individual barriers which reinforce the fuse
clips while providing greater protection
against clip damage and electrical shock.
The unique design permits self-alignment of
clips to fuse cap. This, plus a one-piece clip/
terminal assures low contact resistance.
Multiple units may be broken apart to obtain
desired number of units.
