This device is used in Line-to-Line (also known as across-the-line) applications where DC power feeds are run throughout the Signal House with limited
exposure to the outside elements. It is also an excellent protector for regulated DC Power Supplies, and in that application multiple Model SSS-T516s would be
mounted and wired as close as possible to the power supply. The Model SSS-T516NI should be used liberally throughout the Houses / Cases as part of the Site-Specific
Solutions "Distributed Protection Architecture".
The Model SSS-T516NI is electrically
identical to the Model SSS-T516, but have a more versatile lead dress with different accommodating lead lengths and terminations.
The lead wires are left bare (no Teflon tubing), the terminals are open spade lugs for easy replacement, and the center-to-center spacing is determined by the application.
Note: These are not to be used as Line-to-Ground protectors.
