CABAC BI-METAL LUG 50MM2-REVERSE. 10MM STUD. RBL50-10 x 1/EACH

Description

Reliable Reverse Bi-Metal Performance for Aluminium to Copper Connections

The CABAC Reverse Bi-Metal Lug 50mm² – 10mm Stud (RBL50-10) is designed for secure termination where aluminium conductors need to connect to copper equipment or busbars. Unlike standard bi-metal lugs, this reverse configuration features an aluminium palm and copper barrel, making it ideal for specialised installations where the connection orientation requires the aluminium interface at the termination point.

Manufactured from 99.6% aluminium and 99.9% copper, the lug delivers excellent electrical conductivity while maintaining strong mechanical integrity. The two metals are joined using a friction welding process, creating a solid bond that maintains reliable electrical transfer without risk of separation under load.

For electricians working on switchboards, distribution equipment, or industrial connections, this design ensures dependable performance while maintaining compatibility with common installation practices.

Built for Compliance and Long-Term Electrical Reliability

The CABAC reverse bi-metal lug is engineered to meet multiple international standards, giving contractors confidence when installing equipment across a range of commercial and industrial projects. The lug complies with AS/NZS4325 Part 1 along with recognised international standards including IEC, DIN/VDE, JIS, and BS, supporting safe and compliant installations.

The barrel is chemically treated to minimise contact resistance and corrosion, helping maintain electrical efficiency over the long term. Each lug is also pre-filled with jointing compound, which breaks through aluminium oxide layers during crimping to improve conductivity and reduce the risk of overheating at termination points.

With a fully annealed metal structure and tensile strength of 110 MPa, the lug provides the ductility required for secure crimping while maintaining mechanical strength in demanding environments.

Trade-Friendly Installation with Standard Australian Tooling

Designed for practical use on site, the CABAC RBL50-10 reverse lug is compatible with standard Australian crimp tooling and dies, helping electricians complete terminations quickly without needing specialised equipment.

Tooling interchangeability with CABAC, Utilux, and Burndy systems ensures easy integration into existing toolkits, reducing downtime and keeping installations moving efficiently.

With an operating temperature range of −40°C to +100°C, this lug is suitable for a wide range of electrical environments, from outdoor infrastructure to industrial installations.

Available through iSupply Electrical, contractors benefit from competitive trade pricing, fast ordering, and reliable supply — helping keep projects on schedule without unnecessary procurement delays.
