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.
