CABAC BIMETAL SW/GEACHR CONN 240MM2 BSC240/12K x 1/EACH

Description

Reliable Aluminium-to-Copper Termination for Switchgear Connections

The CABAC Bi-Metal Switchgear Connector 240mm² is designed for terminating aluminium conductors directly onto a 12mm copper switchgear stem, delivering a reliable electrical transition between dissimilar metals. Built for stranded sector and circular stranded aluminium conductors, this connector provides secure current transfer in switchboards and industrial switchgear installations. The connector combines a bi-metal lug with a steel clamping collar, ensuring a strong mechanical and electrical connection while minimising resistance at the joint. The aluminium barrel arrives pre-filled with jointing compound and sealed with a plastic cap, helping protect the connection during installation and reduce the risk of oxidation or contamination on site.

For electricians working on distribution boards, switchgear assemblies, or heavy-duty electrical infrastructure, this connector offers a practical solution for efficient aluminium-to-copper terminations.

High-Quality Bi-Metal Construction for Long-Term Performance

The connector is friction-welded using 99.6% pure aluminium and 99.9% IACS copper, creating a durable bi-metal joint designed to handle demanding electrical loads. This manufacturing method ensures consistent conductivity and structural strength, helping maintain reliable current transfer in high-capacity installations.

A machined slot in the copper stalk allows the 12mm switchgear stem to be inserted directly into the lug. The zinc-plated steel clamping collar with an Allen head grub screw applies controlled pressure between the copper stem and the lug, creating a solid bolted connection for dependable electrical performance.

To further improve reliability, the clamping collar features a cut ring design to prevent eddy currents, reducing potential heat generation in the steel ring during operation. The connector is suitable for operating environments ranging from -40°C to +100°C, making it suitable for a wide range of industrial and commercial switchgear applications.

Australian Standard Compatibility for Fast Trade Installation

Designed to Australian dimensions and tooling, the CABAC BSC240/12K connector can be crimped using standard Australian crimping equipment, allowing electricians to complete installations quickly without specialised tools. Compliance with multiple international standards, including AS 4325 Part 1, ensures the connector meets recognised electrical and mechanical requirements used across commercial and industrial installations.

For contractors managing tight project schedules, using a trusted brand like CABAC means less installation risk, consistent fitment, and faster termination work on site. Combined with iSupply Electrical’s trade-focused supply model, electricians can source reliable switchgear connectors quickly to keep projects moving.
