Bus bar Rittal SV 9640.262, copper, length 851 mm, single piece

Rittal SV 9640.262 is a single-piece copper bus bar with a length of 851 mm and a cross-sectional area of 1354 mm². Engineered for electrical distribution and panel assembly, this rigid copper conductor is intended for use in industrial enclosures and switchgear where a reliable current-carrying path is required. The bar dimensions (45 x 45 mm) and solid construction make it suitable for fixed busbar systems, power distribution and grounding applications within control cabinets and distribution panels.

Advantages

This copper bus bar offers high electrical conductivity and stable mechanical strength thanks to its solid copper construction. Supplied as a single piece, it simplifies installation by reducing the need for joining elements while maintaining a consistent cross section along its length. The 45 x 45 mm profile provides a compact yet robust footprint for mounting inside enclosures and allows for secure bolted connections for feeders, circuit breakers and earthing points.

Suitable for

• Fixed busbar systems in control cabinets and switchgear
• Power distribution between incoming and outgoing feeders
• Grounding and earthing connections in industrial enclosures
• Retrofit or new build electrical panels requiring a solid copper conductor

When it may not be suitable

This rigid, single-piece copper bar is not intended for applications that require frequent disassembly, adjustable-length busbars, or installations where flexible braided connectors are preferred to absorb vibration and movement. It may also be unsuitable where regulations or design require insulated or plated busbars rather than bare copper.

Key specifications

• Material: copper (solid)
• Length: 851 mm
• Profile dimensions: 45 x 45 mm
• Bar cross-section: 1354 mm²
• Supplied as: single piece rigid bus bar

How to use

Install the bus bar inside the enclosure on suitably rated insulators or supports, ensuring correct alignment with cable entry points and switching devices. Secure connections using appropriate bolted terminals and torque settings as specified by the panel or device manufacturer. Verify all electrical clearances and creepage distances meet local standards before energizing, and apply corrosion protection or surface treatment if the environment requires.

What to consider before purchase

• Confirm the required cross-sectional area and current rating for your distribution design
• Check enclosure space and mounting provisions for a 851 mm long, 45 x 45 mm bar
• Verify compatibility with existing connectors, hole patterns and bolt sizes
• Assess environmental conditions (humidity, corrosive atmospheres) and need for additional protection

Usage recommendations

For safe, long-term operation, use appropriately rated insulating supports and follow torque specifications for all bolted connections. Regularly inspect connections for loosening or corrosion and ensure the bar is integrated into a correctly designed protective earthing scheme.
