Electrical enclosure strain relief connector Rittal 9686.260 — screw mounting, copper material

Rittal 9686.260 is a strain relief connector designed for screw mounting in electrical enclosures. Constructed from solid copper and featuring a height of 195 mm, it secures conductors entering cabinets and provides a reliable conductive path for earthing and busbar connections between enclosures. The component is intended for robust mechanical anchoring of main busbar systems and for installations where durable electrical continuity and corrosion-resistant copper conductivity are required.

Advantages

The copper construction offers high electrical conductivity and good corrosion resistance for long-term earthing and busbar connections. Screw-mount installation simplifies assembly into standard enclosure panels and ensures a secure mechanical hold for incoming conductors. Its robust height and solid material provide reliable strain relief under mechanical load and help maintain stable contact for power distribution between cabinets.

Suitable for

• Securing and strain-relieving power conductors entering electrical enclosures
• Connecting main busbar systems between adjacent enclosures
• Providing a conductive, corrosion-resistant earthing point
• Industrial control panels and distribution cabinets requiring durable conductor anchoring

When it may not be suitable

This strain relief connector is specifically a screw-mounted solid copper component sized for applications that can accommodate its 195 mm height. It may not be suitable for installations with severe space constraints, where a smaller or low-profile cable gland or connector is required. It is not intended as an insulating or sealing cable entry gland; additional measures may be needed for environmental sealing or loop protection.

Key specifications

• Material: solid copper for conductive performance
• Mounting method: screw mounting to enclosure panel
• Height: 195 mm
• Function: mechanical strain relief and conductive connection for busbar/earthing

How to use

Mount the connector to the enclosure panel using the designated screw holes, ensuring the mating surfaces are clean and free of paint or debris to maintain good electrical contact. Route the conductor or busbar into the connector and secure with the appropriate fastening screws or clamps as specified by the enclosure and panel layout. Tighten connections to the recommended torque for copper conductors to ensure reliable mechanical retention and electrical continuity. If multiple enclosures are connected, align busbar segments and verify continuity after installation.

What to consider before purchase

• Verify available panel space and that the 195 mm height fits the intended mounting location
• Confirm the connector’s compatibility with conductor cross-sections and the busbar system in use
• Assess whether additional sealing, insulation, or protective measures are required for the installation environment
• Ensure screw-mounting method and hardware are compatible with the enclosure panel thickness

Usage recommendations

For reliable long-term performance, use appropriate copper-compatible fasteners, follow torque specifications for conductor tightening, and inspect connections periodically for signs of corrosion or loosening. Where environmental sealing or mechanical protection is required, combine the connector with suitable gaskets or covers and follow enclosure manufacturer guidelines.
