Narrow Ring Terminal for Use in
High-Density Barrier Terminal Blocks
Applications:
Equipment that utilizes high-density terminal blocks such as
control panels, switch panels, power distribution panels.
Customer Concern:
A manufacturer of switch panels could not nd a source of
ring terminals for connecting #8 AWG wire onto high-density,
space saving barrier terminal blocks with #8 size studs. The
barrier terminal block they were required to use was a new,
high-density barrier terminal block of European design, which
has a reduced width for each stud well to increase the number
of terminations per linear distance. The spacing required a
maximum width of 0.340" for each ring terminal.
Panduit Solution:
#8 AWG Insulated Narrow Ring Terminal
Panduit modied the standard #8 AWG ring terminal to t
within the customer’s high-density barrier terminal block. The
area between the tongue and the barrel was also modied to
eliminate the possibility of arcing between adjacent installed
terminals on the barrier terminal block. The barrel dimensions
were left unchanged so that the same crimp tools could provide
the same crimping characteristics. Panduit also veried that
the narrow ring terminals in the customer’s high-density barrier
terminal block passed static heating tests required by UL 486.
Application Considerations:
Static heating must be tested because of the reduced space
between terminals. Static heating is described as the amount of
temperature rise that occurs when the terminals are operating
for thirty minutes at maximum operating current. Also, minimum
spacing for terminal blocks should not violate UL 1059 Terminal
Blocks, in UL approved applications.
