PPLICATION
The Tri-Barrier product is an original
Thomas & Betts design and we set
new terminal block standards with its
introduction. In recent years, some of
our competition has copied this
design.
It’s easy to see why we’re copied.
Our Tri-Barrier blocks help contain
stray or frayed wire ends. This
prevents electrical shorts — not only
between positions on the same
block, but also between other
components immediately adjacent to
the block. With today’s high-density
PCB designs, this has become an
increasingly important feature.
