CABAC BI-METAL LUG 120MM2-REVERSE RBL120-10 x 1/EACH

Description

High-Performance Reverse Bi-Metal Lug for Reliable Terminations

The CABAC Reverse Bi-Metal Lug 120mm² RBL120-10 is designed for dependable electrical connections where aluminium conductors need to terminate to copper equipment. Unlike standard bi-metal lugs, this reverse design features an aluminium palm and copper barrel, making it suitable for specialised connection requirements in switchboards, distribution equipment, and heavy-duty electrical installations.

Manufactured using 99.6% aluminium and 99.9% copper, the materials deliver strong electrical conductivity and dependable mechanical strength. The friction-welded joint ensures a solid bond between metals, creating a reliable termination point capable of handling demanding electrical loads while maintaining excellent conductivity across the connection.

For electricians working with 120mm² conductors, this lug provides a practical solution that delivers consistent performance across commercial, industrial, and infrastructure projects.

Built for Electrical Reliability and Industry Compliance

Electrical connections need to withstand harsh site conditions, temperature changes, and long-term service loads. CABAC’s reverse bi-metal lug range is manufactured to meet multiple international standards, giving contractors confidence when specifying components for compliant installations.

The friction welding process used in manufacturing creates a strong electrical and mechanical bond that is not subject to electrolysis. This helps maintain connection integrity and prevents premature failure in mixed-metal applications.

The barrel is chemically treated to minimise contact resistance and corrosion, and it comes pre-filled with jointing compound designed to break oxide layers on aluminium conductors during crimping. This improves conductivity and helps ensure a stable long-term connection.

Compliance with recognised standards including AS/NZS4325 Part 1, IEC, DIN/VDE, JIS, and BS provides assurance that the component meets the requirements expected across professional electrical installations.

Trade-Friendly Installation for Faster Job Completion

On busy sites, efficiency matters. The CABAC RBL120-10 lug is designed for straightforward installation using standard Australian crimping tools and dies, helping electricians complete terminations quickly without specialised tooling.

Tooling compatibility across CABAC, Utilux, and Burndy systems makes it easy for contractors to integrate the lug into existing toolkits without extra equipment costs. This reduces installation time and keeps crews moving across multiple tasks on site.

For electrical contractors managing tight project schedules, reliable components that install easily and perform consistently help minimise rework and avoid costly downtime. With CABAC’s proven manufacturing quality and wide acceptance across the trade, this reverse bi-metal lug is a practical choice for professional installations
