Copper conductor roll Rittal SV 9676.504 — copper material, with 13 mm bore

Rittal SV 9676.504 is a copper conductor roll produced from high-conductivity copper, designed for electrical and grounding applications that require reliable metallic conductivity. With a 13 mm bore and a copper finish, the roll is intended for installation in enclosures, busbar systems, grounding points and custom electrical assemblies. Its cylindrical form and material choice make it suitable where a combination of mechanical spacing and electrical conduction is needed.

Advantages

The copper construction provides low electrical resistance and good thermal conductivity, supporting efficient current flow and stable grounding connections. The 13 mm bore allows straightforward mounting on bolts or studs, while the robust copper body resists deformation under normal fastening torque. The product's dimensional compatibility with Maxi-PLS and flat copper bars supports integration into existing busbar or distribution setups.

Suitable for

• Electrical enclosures and control cabinets requiring conductive spacers
• Busbar assemblies and power distribution strips
• Grounding points and earthing connections
• Custom electrical assemblies where a conductive spacer or roll is required

When it may not be suitable

This copper conductor roll is not designed for use in applications where stainless steel or non-conductive insulating spacers are required. It may not be suitable in environments with aggressive chemicals or chlorides that promote copper corrosion unless additional surface protection or isolation is applied.

Key specifications

• Material: copper
• Bore diameter: 13 mm
• Form: cylindrical conductor roll
• Finish: bare copper

How to use

Mount the copper conductor roll on an appropriately sized bolt or stud using the 13 mm bore. Ensure secure mechanical fastening to maintain electrical contact; use suitable torque values for the fastening hardware to avoid deforming the roll. When integrating into busbar or Maxi-PLS assemblies, align the roll with mating conductor surfaces to provide continuous conductive paths and reliable grounding. Where required, clean contact surfaces to remove oxides or contaminants before final assembly for optimal conductivity.

What to consider before purchase

• Compatibility of the 13 mm bore with existing bolts, studs or mounting hardware
• Environmental conditions—risk of corrosion in humid or chemical-exposed locations
• Need for additional surface treatment or isolation to prevent galvanic corrosion with dissimilar metals

Usage recommendations

Use the copper conductor roll in dry or controlled indoor environments when possible, confirm mechanical fit before final installation, and consider protective measures such as insulating washers or coatings if the roll will contact dissimilar metals or corrosive atmospheres.
