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
