CABAC CU CIRC BREAKER LUG 300MM 10MM STUD CALCB300-10 x 1/EACH

Description

High-Conductivity Performance for Demanding Terminations

When you’re terminating large cables into circuit breakers, you need a lug that delivers consistent conductivity and a clean, secure fit. The CABAC CU Circuit Breaker Lug is manufactured from 99.9%+ high-conductivity copper, ensuring excellent current flow and minimal resistance across connections.

Designed with the same barrel dimensions as standard lugs, it allows you to use your existing crimping tools and dies without changing your workflow. The 300mm conductor capacity makes it ideal for heavy-duty applications, while the precision design helps maintain strong electrical performance even in high-load environments.

The added bell mouth entry simplifies insertion of fine-stranded and flexible cables, reducing prep time on site and helping you achieve faster, cleaner terminations.

Built for Compliance, Safety & Long-Term Reliability

On modern switchboards, reduced flashover distances and tighter breaker tunnels can make standard lugs difficult to install. This circuit breaker lug is purpose-built with a narrower palm profile, allowing it to fit seamlessly into 150–250A breakers without modification.

Fully compliant with major international standards including AS/NZS, IEC, DIN/VDE, JIS, BS, and UL/NEMA, it gives you confidence your installation meets regulatory requirements across residential, commercial, and industrial projects.

The lug is tin-plated to resist corrosion and oxidation, supporting long-term durability in a wide range of environments. With an operating temperature range from -55°C to 155°C, it’s built to perform reliably under harsh site conditions, reducing the risk of failures, callbacks, or costly downtime.

Trade-Friendly Design That Saves Time on Site

Time on site is money, and this lug is engineered to make installs faster and more efficient. The bell mouth design reduces cable fraying and speeds up conductor insertion, especially when working with flexible cables commonly used by switchboard builders.

Interchangeable tooling compatibility with CABAC, Utilux, and Burndy systems means no need for additional tooling investment—just grab your existing gear and get the job done.

Backed by a trade-focused supply model with consistent stock availability and fast delivery, this product supports tight project timelines and repeat purchasing. Whether you’re working on a switchboard build, upgrade, or maintenance job, you’ll have the right component on hand to keep things moving without delays.
