CABAC CU CIRC BREAKER LUG 240MM 12MM STUD CALCB240-12 x 1/EACH

Description

High-Conductivity Performance for Demanding Connections

When you’re terminating large conductors into circuit breakers, performance matters. This CABAC copper circuit breaker lug is engineered from 99.9%+ high-conductivity copper, delivering excellent current flow and minimal resistance across your connection points. The fully annealed construction ensures strong crimping results while maintaining flexibility where needed.

The standard barrel dimensions mean you can use your usual crimping tools and dies without changing your workflow—saving time on site. The added bell mouth design is a practical advantage when working with fine-stranded or flexible cables, allowing faster insertion and reducing frustration during tight installs.

Built for Compliance, Safety & Long-Term Reliability

Designed to meet strict international and Australian standards, this lug gives you confidence across residential, commercial, and industrial installs. Manufactured using high-purity copper with tin electroplating, it resists corrosion while maintaining consistent electrical performance over time.

With a wide operating temperature range and strong mechanical properties, it’s built to handle demanding environments without compromising safety. Whether you’re working in switchboards or tight breaker spaces, the narrower palm design ensures proper fitment where standard lugs may fail.

Trade-Ready Design That Saves Time on Site

This lug is purpose-built for electricians who need reliable, no-fuss solutions under tight deadlines. The streamlined design helps eliminate common fitment issues in modern circuit breakers, reducing rework and delays.

Backed by a trusted trade-grade range, it fits seamlessly into fast-paced workflows—whether you’re handling switchboard builds, upgrades, or maintenance jobs. With consistent availability and compatibility across tooling brands, it supports efficient procurement and installation from start to finish.
