Erko ARC 12-50/1 Tubular Aluminum Ring Terminal for 50mm² Conductors

The Erko ARC 12-50/1 is a high-quality tubular ring terminal specifically engineered for the reliable termination of aluminum conductors with a cross-section of 50mm². Designed for professional electrical infrastructure, this terminal features a 12mm mounting hole, providing a secure connection point for power distribution systems and industrial electrical panels. Its robust construction ensures long-term stability and efficient electrical performance in demanding environments.

Advantages

This tubular aluminum ring terminal offers exceptional conductivity and mechanical strength, which are critical for maintaining the integrity of aluminum cable connections. The precision-engineered design facilitates a tight fit, minimizing contact resistance and preventing overheating during operation. Its durable material composition is resistant to environmental stressors, ensuring a consistent and safe electrical path for heavy-duty power applications.

Suitable for

• Terminating 50mm² aluminum conductors in power distribution boards
• Industrial electrical installations requiring secure ring-type connections
• Connecting aluminum cables to busbars or equipment terminals with 12mm studs

When it may not be suitable

This terminal is specifically designed for aluminum conductors and may not be compatible with copper cables due to potential galvanic corrosion issues if not installed with appropriate transition materials. It is also not intended for use in applications requiring a different mounting hole diameter or conductor cross-section size.

Key specifications

• Conductor cross-section: 50mm²
• Mounting hole diameter: 12mm
• Material: Aluminum
• Terminal type: Tubular ring

How to use

To install the Erko ARC 12-50/1, first strip the insulation from the end of the 50mm² aluminum conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for aluminum tubular terminals to ensure a permanent and secure mechanical bond. Once crimped, mount the ring terminal onto the desired 12mm stud and tighten the nut to the manufacturer's specified torque to ensure optimal electrical contact.

What to consider before purchase

• Verify that the conductor cross-section is exactly 50mm²
• Ensure the mounting stud size matches the 12mm hole diameter
• Confirm the compatibility of the terminal material with the existing electrical system
• Use only appropriate crimping tools designed for aluminum tubular terminals

Usage recommendations

Always ensure that the aluminum conductor is properly cleaned and treated with an anti-oxidation contact grease before crimping to prevent oxidation and ensure long-term electrical conductivity.
