Erko ARC Tubular Aluminum Ring Terminal 12mm Hole 150mm² Cross-Section

The Erko ARC tubular aluminum ring terminal is a professional-grade connector engineered for the secure termination of aluminum conductors with a cross-section of 150 mm². Designed for demanding electrical environments, this terminal features a 12 mm mounting hole, facilitating robust connections in power distribution systems and industrial electrical installations. Its tubular construction ensures optimal contact surface area, promoting efficient electrical conductivity and long-term reliability in heavy-duty applications.

Advantages

This terminal offers exceptional durability due to its high-quality aluminum construction, which is specifically chosen to match the material properties of aluminum cables, thereby preventing galvanic corrosion. The precision-engineered tubular design allows for a stable and permanent connection, reducing the risk of overheating or mechanical failure under load. Its standardized dimensions ensure compatibility with common electrical hardware, making it a dependable choice for professionals seeking consistent performance in power infrastructure projects.

Suitable for

• Power distribution cabinets and switchgear
• Industrial electrical infrastructure
• Heavy-duty aluminum cable terminations
• Connection of large cross-section conductors to busbars or studs

When it may not be suitable

This terminal is specifically designed for aluminum conductors and should not be used with copper cables unless appropriate bimetallic transition methods are applied. It is not intended for applications involving high-vibration environments without additional strain relief measures.

Key specifications

• Material: Aluminum
• Conductor cross-section: 150 mm²
• Mounting hole diameter: 12 mm
• Terminal type: Tubular ring terminal

How to use

To install the terminal, first strip the insulation from the aluminum conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade hydraulic crimping tool with the correct die set specified for 150 mm² aluminum terminals to ensure a secure mechanical and electrical bond. Once crimped, verify that the connection is tight and apply appropriate anti-corrosion contact grease if required by local electrical standards.

What to consider before purchase

• Ensure the crimping tool is compatible with 150 mm² aluminum tubular terminals
• Verify the stud size of your equipment matches the 12 mm hole diameter
• Confirm that the cable material is aluminum to prevent electrochemical corrosion

Usage recommendations

Always use a calibrated crimping tool and the correct die size to ensure the integrity of the connection. Inspect the terminal periodically for signs of oxidation or mechanical stress in high-load environments.
