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

Tin plated phosphorus bronze except
for 354900 series which is tin plated
