CABAC CIRC BREAKER 400MM 12MM S 33MM WIDE PALM CALCB400-12 x 1/EACH

Description

Performance & Tight-Fit Termination Efficiency

When space is limited inside modern circuit breakers, this lug is built to solve the problem. The narrow palm design allows clean fitment into compact breaker tunnels where conventional lugs can struggle to seat correctly—helping you avoid rework and installation delays on site.

Made from high-conductivity copper, it delivers strong electrical performance for demanding applications, supporting reliable current transfer across large cable terminations. The bell-mouth entry also makes it easier to guide fine stranded conductors into the barrel, speeding up prep and crimping on busy jobs.

Compliance & Long-Term Electrical Reliability

Manufactured from 99.95% pure copper and engineered for consistent electrical performance, this lug supports dependable, long-life terminations across commercial and industrial installations.

With compliance to major international standards including AS/NZS and IEC frameworks, it provides confidence for contractors working on regulated projects where safety and conformity are non-negotiable. The tin-plated finish helps enhance corrosion resistance, supporting durability in switchboards and distribution environments.

Designed to maintain integrity under demanding conditions, it performs reliably across a wide operating temperature range, making it suitable for diverse installation environments.

Trade Convenience & Faster Installations

Built with electricians and switchboard builders in mind, this lug follows standard crimping practices using compatible tooling across CABAC, Utilux, and Burndy systems—helping reduce downtime on-site and simplifying inventory management.

Its consistent barrel dimensions mean installers can rely on familiar crimping dies for fast, repeatable terminations without extra tooling complications. Ideal for contractors managing multiple projects, it helps keep installs moving and reduces time spent troubleshooting fitment issues.

Available through iSupply Electrical, giving trades access to fast procurement, competitive pricing, and a reliable supply chain for critical switchboard components.
