Ergom KRA 120/12 Sealed Aluminum Ring Terminal

The Ergom KRA 120/12 is a high-quality sealed aluminum ring terminal engineered to provide secure and reliable electrical connections for aluminum conductors. Designed for professional use, this terminal ensures optimal electrical conductivity while offering robust protection against environmental factors, making it an essential component for demanding electrical installations.

Advantages

This terminal stands out due to its specialized sealed construction, which effectively prevents oxidation and moisture ingress, thereby maintaining the integrity of the connection over long periods. The high-grade aluminum material provides excellent mechanical strength and electrical performance, ensuring that the connection remains stable even under challenging conditions. Its design facilitates a precise fit, reducing the risk of contact resistance and overheating in power distribution systems.

Suitable for

• Professional electrical power distribution systems
• Industrial electrical installations involving aluminum wiring
• Outdoor or high-humidity environments requiring corrosion-resistant terminations
• Infrastructure projects where long-term connection reliability is critical

When it may not be suitable

This terminal is specifically designed for aluminum conductors and should not be used with copper wiring unless appropriate bimetallic transition methods are employed. It is also not intended for low-voltage signal or data transmission applications where different connector types are standard.

Key specifications

• Material: High-conductivity aluminum
• Type: Sealed ring terminal
• Conductor cross-section: 120 mm²
• Stud hole diameter: 12 mm
• Corrosion resistance: Enhanced sealed design

How to use

To install the Ergom KRA 120/12, first prepare the aluminum conductor by stripping the insulation to the appropriate length. Ensure the conductor surface is clean and free of oxidation. Insert the conductor fully into the terminal barrel and use a professional hydraulic crimping tool with the correct die set to ensure a secure, gas-tight connection. Once crimped, the terminal can be bolted onto the contact surface using the 12 mm stud hole, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify the cross-section of your aluminum cable matches the 120 mm² rating
• Ensure the mounting stud size is compatible with the 12 mm hole diameter
• Confirm that you have access to the correct hydraulic crimping tools for aluminum terminals
• Check for compatibility with the specific environment and voltage levels of your installation

Usage recommendations

Always use professional-grade crimping tools and follow standard electrical safety protocols when working with aluminum conductors to ensure a long-lasting and safe connection.
