Bus bar Rittal SV 9684.004, copper, single-piece, length 385 mm

Rittal SV 9684.004 is a single-piece copper bus bar with a length of 385 mm intended for electrical distribution and panel assembly. The solid copper conductor is designed to provide stable current carrying capability and includes an integrated mounting hole to simplify fixation inside switchgear and distribution enclosures. Its compact length and single-piece construction make it suitable for installations where a reliable, low-resistance conductor is required.

Advantages

The solid copper construction offers low electrical resistance and consistent conductivity over time, reducing voltage drop in short-run connections. Supplied as a single piece, the bus bar eliminates the need for additional joints that can increase contact resistance. The integrated mounting hole enables secure mechanical fastening and straightforward alignment during panel assembly. The product’s dimensions and material are compatible with common electrical distribution practices, ensuring predictable thermal and electrical behavior under rated load conditions.

Suitable for

• Short-run power distribution within switchgear and control panels
• Interconnections between circuit breakers, contactors, and distribution blocks
• Retrofit or new-build electrical cabinets requiring a compact copper conductor
• Industrial and commercial electrical installations where a single-piece bus is preferred

When it may not be suitable

This bus bar is a solid, single-piece copper conductor with a fixed length of 385 mm and an integrated mounting hole; it may not be appropriate for applications requiring custom lengths, flexible connections, or multiple tapped points along the conductor. Environments with corrosive atmospheres without additional surface protection, or installations that demand plated or insulated bus bars, may require a different product variant.

Key specifications

• Material: copper (E-Cu, solid conductor)
• Form: single-piece bus bar
• Length: 385 mm
• Integrated mounting hole for fastening
• Intended use: electrical distribution and panel assembly

How to use

Position the bus bar within the electrical cabinet or switchgear at the required mounting point, align the integrated mounting hole with the cabinet rail or mounting plate, and fasten using appropriate hardware rated for the installation. Ensure connections to circuit breakers or terminals are made on clean, flat contact surfaces and tightened to the manufacturer’s recommended torque to maintain low contact resistance. Verify clearances to adjacent components and confirm that the bus bar’s current rating and thermal conditions match the intended load before energizing the circuit.

What to consider before purchase

• Confirm the required bus bar length and whether a fixed 385 mm single-piece conductor fits the cabinet layout
• Verify material suitability (copper) for the local electrical code and environmental conditions
• Check required mounting hardware and whether insulating covers or additional protection are needed
• Ensure the bus bar’s cross-sectional area and ampacity are appropriate for the expected load

Usage recommendations

Use the bus bar in dry, ventilated enclosures with proper torque-controlled terminals, perform periodic inspections of mounting and contact points, and add insulating barriers where live parts are accessible to reduce risk and ensure long-term electrical performance.
