CABAC BIMETAL SW/GEACHR CONN 300MM2 BSC300/12K x 1/EACH

Description

Secure Aluminium-to-Copper Terminations for High-Load Switchgear

The CABAC Bi-Metal Switchgear Connector 300mm² is designed to provide a reliable termination point when connecting aluminium conductors to copper switchgear stems. Built for stranded sector and circular stranded aluminium conductors, this connector allows electricians to safely terminate 300mm² cables onto a 12mm switchgear stem in switchboards, distribution systems, and industrial electrical installations. The connector uses a friction-welded aluminium and copper bi-metal lug, combining the conductivity of copper with the lightweight strength of aluminium. This design helps maintain efficient current transfer while reducing the risk of galvanic corrosion between dissimilar metals. A steel clamping collar with an allen head grub screw secures the switchgear stem firmly into the lug slot, ensuring stable electrical contact even in demanding load environments.

For contractors working on commercial switchboards, industrial control panels, or infrastructure upgrades, this connector provides a practical solution for aluminium cable terminations where copper switchgear stems are standard.

Engineered for Electrical Reliability and Standards Compliance

Reliability is critical in switchgear connections, especially in high-current applications. The CABAC connector range is manufactured using 99.6% pure aluminium and 99.9% IACS copper, delivering strong conductivity and consistent electrical performance across demanding installations.

The aluminium barrel is pre-filled with jointing compound and sealed with a plastic cap, helping protect the conductor interface and improve long-term electrical contact. The clamping collar design incorporates a cut in the zinc-plated steel ring to prevent heat-generating eddy currents from forming, improving safety and operational stability. Designed to meet recognised international standards including AS 4325 Part 1 (Australia), IEC, DIN/VDE, JIS, and BS, this connector supports compliance requirements for electrical installations across commercial and industrial projects. With an operating temperature range of -40°C to +100°C, it is suitable for installations exposed to varying environmental conditions.

Trade-Ready Installation with Standard Australian Tooling

Built for practical job-site installation, the CABAC Bi-Metal Switchgear Connector is manufactured to Australian dimensions, allowing electricians to crimp the connector using standard Australian crimping tooling already used across the trade. This reduces the need for specialised equipment and speeds up termination work during switchboard builds, maintenance tasks, and system upgrades. The secure clamping collar mechanism also allows straightforward installation onto the switchgear stem while ensuring strong mechanical and electrical contact.

For electrical contractors managing tight project timelines, choosing proven trade-grade components helps avoid installation delays, rework, and unnecessary downtime. When sourced through a trade wholesaler with national delivery and local pickup options, these connectors are readily available to keep switchgear work moving on schedule.
