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 1500V., Minimum
Clip/Terminals
Tin plated phosphorus bronze except
for 354900 series which is tin plated
spring brass.
Base
Glass reinforced Thermoplastic.
UL 94V0 flammability rating. The
standard base color is Gray except
for 345 x21 items (single pole
products which include anti-rotation
boss option) where the standard
