Description
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
Dielectric Strength 2200V., Minimum
Clip/Terminals
Tin plated phosphorus bronze except for
354900 series which is tin plated spring
brass.
