2CTH0BRX3780 ABB BRX3780 Multiple Copper Coupling

Why Choose the ABB BRX3780 Multiple Copper Coupling?

The ABB BRX3780 Multiple Copper Coupling is a dedicated conductor connection accessory for external lightning protection systems. Designed for coupling or crossing lightning protection conductors without riveting, it provides a practical mechanical and electrical connection point within compatible down-conductor and earth termination installations.

Unlike ABB's special flat-strip coupling, the BRX3780 multiple coupling accommodates both flat and round conductor arrangements. It is suitable for 30 mm wide flat strips and Ø6 mm or Ø8 mm round conductors, while its multiple-coupling configuration also enables crossings between round conductors.

Manufactured from copper, the BRX3780 is intended for compatible copper conductor systems where dependable electrical continuity is required. The coupling is supplied individually, weighs 0.300 kg and is identified by ABB order code 2CTH0BRX3780.

Flexible Flat and Round Conductor Connections

Reliable conductor continuity is essential throughout an external lightning protection system. The ABB BRX3780 provides a versatile connection point where compatible conductors need to be coupled or crossed, eliminating the need for riveting and allowing 30 mm flat strip and Ø6 mm or Ø8 mm round conductor configurations to be accommodated.

The BRX3780 differs from ABB's standard coupling through its additional ability to support crossings of round conductors. This makes the multiple coupling particularly useful where conductor routes intersect or where different compatible conductor profiles need to be incorporated into the lightning protection network. Conductor materials, dimensions and joint arrangements should always be selected in accordance with the complete lightning protection design.

Typical Applications

• Coupling flat lightning protection conductors.
• Coupling compatible flat and round conductors.
• Crossing Ø6 mm and Ø8 mm round conductors.
• External lightning protection down-conductor systems.
• Lightning protection earth termination networks.
• Commercial and industrial building lightning protection.
• Infrastructure and utility installations.
• Lightning protection installations requiring rivet-free conductor joints.
