Product Description
The INT RU-600-3 is a heavy-duty, triple-barrel mechanical terminal lug designed for high-capacity industrial power distribution. This component allows for the secure termination of up to three large-gauge conductors in a single compact block, making it an essential space-saving solution for panelboards, switchgear, and motor control centers.
Precision-machined from high-strength aluminum alloy and finished with electro-tin plating, this lug ensures a low-resistance connection and superior protection against oxidation. Its CU-AL dual-rating provides total flexibility, allowing for use with both copper and aluminum conductors.

Key Features & Benefits
-
Triple Conductor Capacity: Streamlines wiring by allowing three separate cables to be terminated on a single mounting point, significantly reducing the footprint on busbars.
-
Dual-Rated Versatility: Certified for use with both Copper (Cu) and Aluminum (Al) conductors, minimizing the need for multiple part types on-site.
-
Robust Mechanical Connection: Utilizes high-pressure set screws to ensure a gas-tight electrical bond without the need for specialized hydraulic crimping tools.
-
Superior Corrosion Resistance: The tin-plated finish prevents galvanic corrosion, especially important when joining dissimilar metals (aluminum lugs to copper busbars).
-
Industrial Durability: Designed to handle the high thermal and mechanical stresses associated with 600 MCM cabling in commercial and industrial settings.
Technical Installation Tips
-
Torque Requirement: For 600 MCM conductors, typical installation torque ranges from 375 to 500 in-lbs. Always check the specific manufacturer labeling for final torque values to ensure a safe connection.
-
Wire Preparation: For aluminum conductors, it is highly recommended to use a quality oxide inhibitor (like Penetrox) to ensure long-term electrical stability.
-
Space Management: The single-hole mounting design is ideal for retrofitting existing panels where busbar space is limited but multiple cable feeds are required.
