354 Series OMMI-BLOK® Molded Base Fuse Block for 3AG Fuses
Product Characteristics
Compatible Fuses Size 3AB/AG
Description
Product & Mounting Dimensions
Dielectric Strength 1500V., Minimum
A low profile fuse block featuring
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. Higher currect ratings
have been attained using spring
brass clips. With the exception of
the two-pole unit, multiple pole
units may be broken apart to obtain
desired number of poles
Option
Two different style clips can be supplied for circuit identity or
polarization. Contact Littelfuse.
Agency Approval
