Ergom KDA 120/12 Aluminum Ring Terminal

The Ergom KDA 120/12 aluminum ring terminal is a professional-grade electrical component engineered for reliable termination of aluminum conductors. Designed to accommodate 120 mm² cables, this terminal provides a secure and stable connection point for power distribution systems, ensuring optimal electrical conductivity and long-term mechanical durability in demanding industrial environments.

Advantages

This terminal is manufactured from high-quality aluminum, which offers excellent electrical properties and resistance to corrosion when installed correctly. Its robust construction ensures that the connection remains stable under mechanical stress, minimizing the risk of overheating or signal loss. The precise design of the ring terminal facilitates a firm attachment to busbars or studs, making it a dependable choice for heavy-duty electrical infrastructure projects.

Suitable for

• Power distribution cabinets and switchgear
• Industrial electrical installations
• Connection of large-gauge aluminum conductors
• Infrastructure projects requiring secure bolt-down terminations

This terminal may not be suitable for applications involving copper conductors without appropriate bimetallic transition adapters, as direct contact between copper and aluminum can lead to galvanic corrosion. It is also not intended for use in environments where the terminal will be subjected to extreme chemical exposure or high-vibration conditions that exceed the mechanical rating of the aluminum material.

Key specifications

• Material: Aluminum
• Conductor cross-section: 120 mm²
• Stud hole diameter: 12 mm
• Terminal type: Ring terminal

To use the Ergom KDA 120/12, first strip the insulation from the aluminum conductor to the appropriate length. Insert the conductor fully into the terminal barrel and use a professional hydraulic crimping tool compatible with aluminum terminals to ensure a gas-tight connection. Once crimped, secure the ring end to the desired stud or busbar using a matching bolt and nut, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Ensure the conductor cross-section matches the 120 mm² rating
• Verify that the stud size is compatible with the 12 mm hole
• Confirm the compatibility of the terminal material with the conductor type
• Use appropriate crimping tools designed for aluminum connectors

Usage recommendations: Always apply an anti-oxidation contact grease to the aluminum conductor before crimping to prevent oxidation and ensure long-term electrical performance. Regularly inspect the connection point for signs of thermal stress or loosening after the initial installation.
