ALNS-350-12

Overview

The Ilsco ALNS-350-12 is a compression-type aluminum-to-copper transition connector designed for joining stranded aluminum conductors to copper terminals or lugs. It features a dual-metal barrel configuration with an internal zinc-aluminum insert that ensures reliable electrical continuity between dissimilar metals. The connector utilizes a hexagonal body for secure tool engagement during installation, facilitating proper crimping pressure distribution. This component serves as a critical junction in electrical systems where aluminum wiring must interface with copper equipment, preventing galvanic corrosion and maintaining low resistance connections under standard industrial voltage ratings.

Feature Summary

• Dual-metal construction with integrated zinc-aluminum insert for dissimilar metal compatibility
• Compression design ensuring uniform crimping force and mechanical stability
• Hexagonal barrel geometry optimized for standard hydraulic or manual crimping tools

Applications

• Connecting stranded aluminum feeders to copper busbars or terminal blocks
• Junction points in commercial and industrial electrical distribution panels
• Transformer and switchgear installations requiring aluminum-to-copper transitions

Procurement Notes

Verify that the specific batch matches the required conductor size range and insulation type before purchase. Confirm compliance with relevant industry standards such as UL or CSA for the intended application region. Ensure crimping tools are calibrated and compatible with the hex dimensions specified by the manufacturer to guarantee connection integrity.

Selection Notes

Select this connector when transitioning from aluminum conductors to copper termination points. Ensure the conductor gauge aligns with the connector's rated capacity. Consider environmental conditions and whether additional sealing or coating is required for outdoor or corrosive settings beyond the standard material properties.

Part Context

Ilsco manufactures a comprehensive range of compression connectors for power distribution. The ALNS series specifically addresses the technical challenges of connecting aluminum wire to copper hardware, a common requirement in modern electrical infrastructure upgrades and new constructions involving mixed metal wiring systems.

Replacement Considerations

Consult official cross-reference guides for equivalent dual-metal compression connectors from other manufacturers. Verify that any substitute part meets the same electrical and mechanical performance standards for aluminum-to-copper transitions.
