Why Choose the Rittal SV 3570.005 Laminated Copper Bar?
The Rittal SV 3570.005 is a flexible laminated copper bar designed for reliable high-current connections within industrial switchgear and power distribution systems. Manufactured from high-purity F20 electrolytic copper, it combines excellent electrical conductivity with the flexibility required for compact and adaptable power connections.
The bar has an overall cross-section of 20 × 5 mm and consists of five 20 × 1 mm copper laminae. Its 2,000 mm length may be individually cut to suit the installation, making it suitable for customised connections between busbars, switchgear components and other high-current electrical equipment.
A highly resistant vinyl insulation surrounds the laminated conductor, offering a temperature range from -30 °C to +105 °C, fire protection corresponding to UL 94 V-0 and a dielectric strength of 20 kV/mm. Depending on the permitted temperature rise, Rittal specifies rated currents from 330 A at 30 K to 525 A at 70 K.

Flexible High-Current Connections for Power Distribution
Laminated copper bars provide an effective alternative to rigid copper busbars and large power cables where flexibility, compact routing and high current-carrying capacity are required. Multiple thin copper laminae allow the conductor to flex more readily while retaining the conductivity needed for demanding industrial electrical connections.
The Rittal SV 3570.005 combines five 20 × 1 mm F20 copper laminae into an insulated 20 × 5 mm conductor. Its 2,000 mm supplied length can be shortened to suit individual installations, while rated current values of 330 A, 435 A and 525 A are specified for temperature rises of 30 K, 50 K and 70 K respectively.
Typical Applications
- Industrial power distribution assemblies.
- Flexible connections between busbar systems and switchgear.
- High-current electrical connections within control cabinets.
- Connections requiring compensation for installation tolerances or movement.
- Electrical switchgear and distribution panels.
- Machine building and OEM power systems.
- Industrial automation equipment.
- Professional panel-building installations.
