Product information

Description

The Klauke 4R5 Tubular Ring Lug is a high-quality electrical terminal engineered for professional wiring and secure power distribution applications. Designed specifically for 25 mm² conductors and an M5 stud size, this reliable component ensures optimal electrical connectivity and long-term mechanical stability in demanding industrial environments.

Advantages

This tubular ring lug features durable tin plating that provides exceptional resistance against corrosion and oxidation, ensuring a stable connection over extended periods of use. The straight connector design facilitates straightforward alignment and mounting during installation. Manufactured by Gustav Klauke GmbH, the component meets high standards of electrical engineering, delivering consistent performance in switchgear assembly and industrial wiring tasks.

Suitable for

  • Electrical installations requiring 25 mm² wire connection
  • Switchgear assembly and control panel wiring
  • Industrial power distribution systems
  • Professional maintenance and repair projects

When it may not be suitable

This product may not be suitable for wire sizes significantly larger or smaller than 25 mm², as an improper fit can compromise the integrity of the electrical connection. Additionally, applications requiring bolt sizes other than M5 will not be compatible with this specific ring lug.

Key specifications

  • Product type: Tubular ring lug
  • Connector contacts plating: Tin
  • Connector type: Straight
  • Compatible wire cross-section: 25 mm²
  • Stud size compatibility: M5

How to use

To use the Klauke 4R5 tubular ring lug, first prepare the wire by stripping the insulation to the appropriate length to expose the 25 mm² conductor. Insert the stripped conductor fully into the tubular barrel of the terminal. Secure the conductor using a compatible crimping tool designed for tubular cable lugs to ensure a permanent and reliable mechanical and electrical bond. Finally, place the ring terminal over the M5 threaded stud and fasten it securely with a matching nut or fastener.

What to consider before purchase

  • Verify that your conductor cross-section matches the 25 mm² specification
  • Check that your mounting bolt corresponds to the M5 stud size
  • Ensure you have the correct crimping tool for tubular ring lugs
  • Confirm the environmental conditions match the tin-plated brass or copper capabilities

Usage recommendations

Always use the manufacturer-approved crimping tool to attach the 25 mm² wire to the Klauke 4R5 terminal, and ensure the M5 stud is tightened to the recommended torque specification for safe and reliable electrical operation.
