Electrical enclosure mounting bracket Rittal 9686.549 — copper, bronze colour, height 180 mm

Rittal 9686.549 is an electrical enclosure mounting bracket made of copper with a bronze-coloured finish and a nominal height of 180 mm. Designed for use inside distribution and control enclosures, the bracket provides a conductive, corrosion-resistant mounting and bonding point suitable for PE/PEN connection and earthing applications. The solid construction and weight of approximately 1.24 kg indicate a robust component intended for long-term installation in industrial and commercial electrical cabinets.

Advantages

The copper material ensures low electrical resistance and reliable conductivity for protective earth (PE) and combined PE/PEN bonding. A bronze-coloured surface finish enhances corrosion resistance while maintaining the conductive properties of the base metal. The 180 mm height and purpose-built geometry facilitate secure fastening to enclosure walls and integration with busbars, angle brackets and baying brackets in tested system configurations compliant with IEC 61439-1 standards.

Suitable for

• Internal bonding and earthing points in distribution and control enclosures
• PE/PEN busbar and baying bracket assemblies in switchgear and distribution boards
• Installations requiring corrosion-resistant conductive mounting hardware

When it may not be suitable

This bracket is intended primarily for internal enclosure use and may not be appropriate where non-conductive or insulated mounting elements are required. It is not a finished external architectural component and may not meet aesthetic or mechanical requirements for exposed structural mounting outside electrical cabinets.

Key specifications

• Material: copper (conductive)
• Surface finish: bronze-coloured
• Height: 180 mm
• Applicable for PE/PEN bonding and mounting
• Weight: approximately 1.24 kg
• Compatible with busbar, angle bracket and baying bracket assemblies for tested IEC 61439-1 configurations

How to use

Mount the bracket inside the enclosure at the required position using the designated fixing points. Ensure secure mechanical fastening to the enclosure wall and establish a low-resistance electrical connection to protective earth or PEN conductors using appropriately sized fasteners and cables. When integrating with busbars or baying brackets, follow the system layout and tightening torques specified by the enclosure or system manufacturer. Verify continuity and torque after installation and re-check after any modifications.

What to consider before purchase

• Confirm that a conductive copper bracket is appropriate for the intended earthing or bonding application.
• Verify physical dimensions and mounting hole positions against the enclosure layout.
• Ensure compatibility with existing busbars, angle brackets and baying systems in the cabinet.
• Check environmental and corrosion requirements for the installation location.

Usage recommendations

Use appropriate corrosion-resistant fasteners and ensure metal-to-metal contact for reliable earth continuity. Test electrical continuity after installation and include the bracket in routine maintenance inspections of the enclosure earthing system.
