Why Choose the Rittal SV 3586.020 CUPONAL Busbar?
The Rittal SV 3586.020 is a CUPONAL copper-coated aluminium busbar designed for industrial electrical power distribution systems. Combining an aluminium core with a copper outer layer, CUPONAL construction provides a practical alternative to solid copper busbars while retaining a copper contact surface for compatible connection components.
Measuring 30 × 10 mm with an overall length of 2,400 mm, the SV 3586.020 is rated for a maximum current of 493 A. Rittal specifies this current rating at a busbar temperature of 65 °C and an ambient temperature of 35 °C, with correction factors available in accordance with DIN EN 43 671 for different operating conditions.
The busbar is suitable for configuring distribution systems using Rittal SV 9340.000 and SV 9340.050 busbar supports. Its 2,400 mm supplied length may be individually cut to suit the required installation, providing flexibility when constructing switchgear, control panels and other industrial distribution assemblies.

CUPONAL Busbars for Industrial Power Distribution
CUPONAL busbars combine the reduced material weight of an aluminium core with a copper outer layer, providing a conductive copper contact surface for compatible electrical connections. This construction makes them suitable for structured industrial power distribution systems where both electrical performance and efficient material use are important.
The Rittal SV 3586.020 provides a 30 × 10 mm conductor profile with a maximum rated current of 493 A under Rittal's specified reference conditions. When combined with SV 9340.000 or SV 9340.050 busbar supports, it can be used to create modular distribution arrangements and may be cut from its 2,400 mm supplied length to meet individual installation requirements.
Typical Applications
- Industrial electrical power distribution.
- Busbar systems using Rittal SV 9340.000 or SV 9340.050 supports.
- Switchgear and distribution panels.
- Industrial control cabinets.
- Main and branch power distribution assemblies.
- Machine building and OEM electrical systems.
- Factory automation and production equipment.
- Professional panel-building installations.
