Ergom KRA 300/12 Sealed Aluminum Ring Terminal

The Ergom KRA 300/12 is a professional-grade sealed aluminum ring terminal engineered for secure and efficient electrical terminations. Designed to handle demanding industrial environments, this terminal provides a robust connection for aluminum conductors, ensuring optimal electrical conductivity and long-term reliability in power distribution systems.

Advantages

This terminal features a specialized sealed construction that effectively protects the connection point from environmental degradation, such as oxidation and moisture ingress. The high-quality aluminum material is selected for its excellent balance of weight and conductivity, making it an ideal choice for heavy-duty electrical installations where performance and durability are critical. Its precise design facilitates a stable contact surface, minimizing resistance and preventing overheating during operation.

Suitable for

• Industrial power distribution systems
• Terminating large-gauge aluminum conductors
• Heavy-duty electrical infrastructure projects
• Applications requiring environmental protection for cable connections

When it may not be suitable

This terminal is specifically designed for aluminum conductors and may not be suitable for direct connection to copper conductors without appropriate bimetallic transition adapters. It is also not intended for use in high-vibration environments where specialized locking mechanisms might be required.

Key specifications

• Material: High-conductivity aluminum
• Type: Sealed ring terminal
• Conductor cross-section: 300 mm²
• Stud hole diameter: 12 mm
• Design: Corrosion-resistant sealed structure

How to use

To install the Ergom KRA 300/12, first strip the insulation from the aluminum conductor to the appropriate length. Insert the conductor fully into the terminal barrel. Use a compatible hydraulic crimping tool with the correct die set to ensure a permanent, gas-tight mechanical connection. Ensure the terminal is securely fastened to the busbar or contact point using a 12 mm bolt, ensuring the contact surface is clean and free of debris.

What to consider before purchase

• Verify the cross-section of your aluminum cable matches the 300 mm² specification.
• Ensure the 12 mm stud hole size is compatible with your connection point.
• Confirm the use of proper crimping tools for aluminum terminals.
• Check for the necessity of antioxidant joint compound to prevent oxidation.

Usage recommendations

Always use professional-grade hydraulic crimping equipment to ensure the integrity of the connection. Regularly inspect the terminal after installation to ensure no signs of thermal stress or loosening occur in the electrical system.
