Mounting bracket for electrical enclosure Rittal 9686.539 — copper, bronze colour, length 180 mm

Rittal 9686.539 mounting bracket is an accessory for electrical enclosures made from copper with a bronze-colour finish. At 180 mm length and weighing approximately 960 g, it is intended for secure mechanical attachment and for PE/PEN connection tasks within switchgear and distribution cabinets. The product forms part of a PE/PEN combination that includes a busbar and angle bracket, enabling type-tested configurations compliant with IEC 61439-1 when installed as part of the specified system.

Advantages

The copper construction provides good electrical conductivity and corrosion resistance for earthing and protective conductor applications. The bronze-colour finish gives a uniform appearance that integrates with metal enclosures while protecting the base material. Its 180 mm length and robust build support reliable mechanical fixation and conductor clamping in panel installations.

Suitable for

• Mounting and earthing (PE/PEN) in switchgear and distribution cabinets
• Use as a baying/bracing bracket in electrical panels
• Integration into type-tested PE/PEN busbar configurations to IEC 61439-1
• Panel assembly and conductor termination where copper conductive elements are required

When it may not be suitable

This mounting bracket is not intended as an isolated component for applications that require alternative base materials (for example stainless steel or aluminium) due to different mechanical or corrosion performance needs. It should not be used outside its intended role in electrical enclosures or where specific certification beyond IEC 61439-1 system compliance is required unless the full assembly and installation meet those regulations.

Key specifications

• Material: copper
• Finish: bronze-colour
• Length: 180 mm
• Cross-section / mounting face: 30 x 10 mm (height x width)
• Weight: approximately 960 g
• Application: PE/PEN connection, mounting in switchgear and distribution cabinets
• Compatibility: designed for use in type-tested PE/PEN busbar assemblies compliant with IEC 61439-1

How to use

Install the bracket on the enclosure mounting surface according to the enclosure and busbar manufacturer's assembly instructions. Ensure secure mechanical fastening and correct alignment with the associated busbar and angle bracket. Make PE or PEN conductor terminations using appropriate bolts, washers and torque values recommended by the enclosure or earthing system documentation. Verify conductor continuity and mechanical tightness after installation and before energising the panel.

What to consider before purchase

• Confirm material suitability (copper) for the intended environmental and electrical conditions
• Verify the bracket dimensions (180 mm length, 30 x 10 mm mounting face) fit your enclosure and busbar layout
• Ensure the product is compatible with the PE/PEN busbar system and meets your requirement for IEC 61439-1 type-tested configurations when used as part of the certified assembly
• Check required hardware (fasteners, washers, torque settings) and local regulations for earthing connections

Usage recommendations

Follow manufacturer's guidance for installation torque and assembly order, use corrosion-inhibiting washers where required in mixed-metal interfaces, and perform continuity and mechanical checks as part of final panel verification to maintain reliable PE/PEN connections.
