Erko ARC Tubular Aluminum Ring Terminal 12mm Hole for 185mm² Cable

The Erko ARC tubular aluminum ring terminal is a professional-grade connector engineered for the reliable termination of aluminum conductors with a cross-section of 185 mm². Designed for demanding electrical environments, this terminal features a 12 mm mounting hole, ensuring compatibility with standard bolt sizes in power distribution systems. Its robust construction provides excellent electrical conductivity and mechanical stability, making it an essential component for maintaining secure connections in industrial and infrastructure power networks.

Advantages

This terminal offers superior performance due to its high-quality aluminum composition, which is specifically optimized for aluminum cable termination. The tubular design facilitates a secure crimping process, ensuring a low-resistance electrical path that minimizes energy loss and prevents overheating. Its durable build quality guarantees long-term reliability even under challenging operational conditions, providing a stable solution for heavy-duty electrical installations.

Suitable for

• Power distribution systems
• Industrial electrical infrastructure
• Large-scale electrical panel wiring
• Utility and grid connection projects

This terminal is not suitable for copper conductors, as using aluminum connectors with copper cables can lead to galvanic corrosion and connection failure. It is also not intended for applications requiring high-flexibility fine-stranded cables unless specifically rated for such use.

Key specifications

• Material: Aluminum
• Cable cross-section: 185 mm²
• Mounting hole diameter: 12 mm
• Terminal type: Tubular ring terminal

To use the terminal, ensure the aluminum conductor is properly stripped to the required length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade hydraulic crimping tool compatible with aluminum tubular terminals to perform the crimp according to the manufacturer's specifications. Ensure the connection point on the busbar or equipment is clean and free of oxidation before securing the terminal with a 12 mm bolt.

What to consider before purchase

• Verify the cross-section of your aluminum cable matches the 185 mm² specification.
• Ensure the 12 mm mounting hole is compatible with your existing connection hardware.
• Confirm that your crimping equipment is suitable for aluminum tubular terminals.
• Check for compatibility with the specific environmental conditions of your installation site.

Usage recommendations: Always apply an appropriate contact grease designed for aluminum connections to prevent oxidation and ensure long-term electrical integrity. Regularly inspect the connection for signs of thermal stress or loosening after the initial installation period.
