Bus bar Rittal SV 9686.546 copper 2 pcs 500 mm

Rittal SV 9686.546 copper bus bar set (2 pcs, 500 mm) is a pair of electrolytic copper conductors designed for PE/PEN distribution and earthing inside electrical enclosures. Manufactured from E-Cu (electrolytic copper) to DIN EN 13601 standards and supplied with integral punchings, these 40 x 10 mm bars provide a compact, low-resistance connection option for industrial control cabinets, switchgear and distribution panels where robust protective earth and combined protective earth-neutral conductors are required.

Advantages

The bus bars offer high conductivity and corrosion resistance typical of electrolytic copper, ensuring reliable low-loss current flow for earthing and PE/PEN applications. Their 40 x 10 mm cross section and 500 mm length make installation straightforward in standard enclosure layouts, while the integral punchings simplify attachment of cables, terminals and auxiliary components. Compliance with DIN EN standards supports consistent mechanical and electrical performance.

Suitable for

• Protective earth (PE) and combined protective earth-neutral (PEN) distribution in switchgear and distribution panels
• Earthing and equipotential bonding inside industrial control cabinets
• Retrofit or new-build electrical enclosures requiring copper main earth rails

When it may not be suitable

This copper bus bar set is intended for PE/PEN applications and is not designed for use as a live-phase conductor. It may be unsuitable where insulation, phase segregation or specific color-coding requirements are mandated by local wiring regulations. For installations requiring insulated bus bars, non-conductive covers, or different cross sections for higher current ratings, choose a product specifically designed for those conditions.

Key specifications

• Material: Electrolytic copper (E-Cu)
• Quantity: 2 pieces
• Cross section: 40 x 10 mm
• Length: 500 mm
• Standard: Manufactured to DIN EN 13601
• Features: Integral punchings for fixing and cable termination

How to use

Mount the bus bars on the enclosure mounting plate or standoffs using appropriate insulated washers and fastening hardware. Align the integral punchings with the required cable entry points and secure conductors or terminals with properly rated bolts and washers sized to match the punched holes. Ensure all connections are tightened to the torque specified for the chosen fasteners and that protective earthing continuity is verified with a suitable low-resistance tester after installation. If bus bar covers are required by regulation or for added safety, install them following the cover manufacturer’s instructions.

What to consider before purchase

• Confirm that a 40 x 10 mm copper cross section and 500 mm length meet your current-carrying and mechanical requirements
• Verify PE/PEN usage is appropriate for your local electrical code and system configuration
• Check that required mounting space and hole alignment in the enclosure match the integral punchings
• Plan for protective covers or insulation if regulations or safety policies require it

Usage recommendations

Use the bus bars exclusively for protective earth or combined PE/PEN connections, follow local earthing regulations, torque fasteners to recommended values, and perform continuity and resistance measurements after installation to confirm proper grounding.
