The CRL12050 Copper Reducing Link is a heavy-duty, precision-engineered connector designed to transition safely and efficiently between 120 mm² and 50 mm² copper conductors. Manufactured from 99.95% pure, fully annealed copper, it is ideal for use in large commercial switchboards, main switch panels, sub-distribution boards, and high-load service applications.
This reducing link supports circular and sector stranded copper conductors and is crimp-compatible with standard Australian/NZ hex dies. With an impermeable barrier to oils and moisture, it ensures reliable electrical continuity even in demanding conditions.
Key Features
- Large Gauge Reduction – Transitions from 120 mm² to 50 mm² for high-current distribution applications
- High-Purity Copper (99.95%) – Delivers excellent conductivity and long-term reliability
- Full Anneal Finish – Provides 200 MPa tensile strength and 40% ductility for mechanical integrity and flexibility
- Crimp-Ready – Compatible with standard Australian/NZ hex crimp dies for simple and compliant installation
- Oil & Moisture Resistant – Internal impermeable barrier protects connection from contamination
- Stranded Conductor Support – Works with circular and sector stranded copper conductors

- Service upgrades or retrofit projects where conductor sizes must be adjusted
- High-current environments requiring secure, low-resistance copper transitions
- Power distribution boards requiring accurate gauge matching for safe terminations
When safety, conductivity, and compliance matter most, the CRL12050 Copper Reducing Link delivers. Designed for high-capacity installations where large-to-medium cable transitions are needed, it's the preferred solution for professional electricians working on switchboard, mains, and industrial wiring systems.
Q. Can I crimp this with a standard hex die?
A. Yes — this link is fully compatible with standard Australian and New Zealand hex dies used for copper lugs and links.
Q. What types of copper cables does it support?
A. It supports both circular and sector stranded copper conductors, commonly used in switchboards and feeders.
Q. Is it suitable for outdoor use?
A. While the copper body includes an impermeable oil and moisture barrier, the overall installation should be housed in an IP-rated enclosure if installed outdoors.
Q. Why use a reducing link instead of a terminal block?
A. Reducing links provide a low-resistance, high-integrity mechanical bond, minimising heat build-up and ensuring reliable power transfer across mismatched cable sizes.
