Description
High-Performance Termination for Large Cables
Designed specifically for modern switchgear, the CABAC copper circuit breaker lug delivers reliable termination where space is tight and performance matters. With reduced flashover distances in todayâs breakers, standard lugs often wonât fit â this purpose-built design solves that problem with a narrower palm while maintaining full conductor capacity.
The 300mm² barrel supports large cable terminations without compromise, while the bell mouth entry makes it significantly easier to insert fine-stranded or flexible conductors on-site. That means faster installs, fewer reworks, and cleaner terminations â especially in high-demand commercial and industrial environments.
Built for Reliability & Compliance
Manufactured from 99.9%+ high-conductivity copper and finished with a durable tin plating, this lug ensures excellent electrical performance and long-term corrosion resistance. Fully annealed copper provides superior ductility, making crimping more consistent and reducing the risk of cracking under load.
Compliant with major international standards including AS/NZS, IEC, DIN/VDE, JIS, BS, and UL/NEMA, this lug is suitable for a wide range of regulated installations. Whether you’re working on switchboards, distribution systems, or industrial panels, you can install with confidence knowing it meets strict compliance requirements.
Trade-Ready Design for Faster Installs
Built with the needs of electricians and contractors in mind, this lug supports standard crimping practices using interchangeable tooling with major brands. That means no special setup, no wasted time â just grab the right die and get the job done.
Ideal for switchboard builders and contractors working with flexible cable, the bell mouth design reduces installation friction and speeds up cable prep. With consistent stock availability and single-unit supply, itâs easy to order exactly what you need for the job without delays or excess inventory.
