Solder & Q.C.Types:
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 termi-
nals 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 pole units may be broken
apart to obtain desired number of poles.
APPROVALS:
Recognized under the Components Program of
Underwriters Laboratories and Certified by CSA.
