Cable clamp Rittal SV 9640.325 — silver, maximum bundle diameter 30 cm, 1 pc

Rittal SV 9640.325 cable clamp is a heavy-duty metallic clamp designed for secure connection and support of round conductors made of copper or aluminium with cross-sections from 95 to 300 mm². The clamp is finished in silver and supplied as a single piece with a total weight of approximately 400 g. It accommodates large cable bundles up to 30 cm in diameter and is intended for use in electrical installations and switchgear assemblies where robust conductor termination is required.

Advantages

The clamp offers a sturdy metallic construction that provides reliable mechanical support and electrical continuity for single-wire and multi-wire round conductors. Its design accepts a wide range of conductor sizes (95–300 mm²) and supports large bundle diameters up to 30 cm, reducing the need for multiple clamps in bulky cable entries. Being a single-piece silver-finished clamp simplifies inventory and installation in industrial environments.

Suitable for

• Connection and routing of large copper or aluminium round conductors (95–300 mm²)
• Termination points in switchboards, distribution panels and industrial control cabinets
• Instances where large cable bundles (up to 30 cm diameter) must be secured

When it may not be suitable

The clamp is intended for round conductors in the specified cross-section range; it may not fit smaller conductors below 95 mm² or flat/rectangular busbars. For applications requiring insulation, integrated sealing, or vibration-damping materials, this metallic clamp alone may not provide the necessary features and additional accessories or different clamp types should be considered.

Key specifications

• Compatible conductor material: Copper (Cu) and Aluminium (Al)
• Compatible conductor cross-section: 95–300 mm² (single-wire and multi-wire round conductors)
• Maximum bundle diameter: 300 mm
• Finish/color: Silver
• Unit weight: ~400 g
• Quantity per pack: 1 piece

How to use

Position the clamp around the round conductor bundle or individual conductor sized within the specified range, then secure it using the appropriate fastening hardware and torque values recommended for the installation. Ensure conductor surfaces are clean and free of corrosion before making electrical connections. Verify mechanical tightness and electrical continuity after installation and, if needed, add protective treatments or insulation where the clamp contacts the conductor.

What to consider before purchase

• Confirm conductor type and cross-section fall within 95–300 mm²
• Check that a maximum bundle diameter of 300 mm matches your cable grouping needs
• Determine whether additional insulation, sealing or vibration-damping accessories are required
• Ensure compatibility with your panel or mounting hardware and required torque specifications

Usage recommendations

Use the clamp for secure terminations of large round conductors in switchgear and distribution panels; clean contact surfaces before installation and follow standard industry torque and safety procedures to ensure reliable electrical and mechanical performance.
