Dual-Rated Aluminum Mechanical Lug — One Hole, 600 kcmil–2 AWG
CT Part No. CT-T1H1-600 • SKU 210-99009 • AL9CU Dual Rated
The CT-T1H1-600 is a single-conductor, one-hole mechanical connector machined from 6061-T6 aluminum alloy and electro-tin plated for corrosion resistance and low contact resistance. Dual rated AL9CU, it terminates both aluminum and copper conductors from 600 kcmil through 2 AWG using a slotted aluminum set screw — no special tooling or dies required. The one-hole pad accepts standard 3/8 in mounting hardware for panelboard, switchgear, transformer, and grounding terminations.
