2CTH0RPO2840 ABB RPO2840 Duck Foot Connector

Why Choose the ABB 2CTH0RPO2840 Duck Foot Connector?

The ABB 2CTH0RPO2840 is a robust duck foot connector for external lightning protection earthing systems, designed to provide reliable connections between multiple strands of flat earthing conductor. Identified by ABB as type RPO2840, it forms part of the ABB external lightning protection range and is specifically intended for constructing duck-foot earth termination arrangements.

Manufactured from zinc-plated die-cast brass, the connector enables three or four strands of 30 × 2 mm tin-plated copper strip to be joined while allowing variable conductor angles. This makes it particularly suitable for fan-shaped earth termination layouts where conductors need to branch away from a common connection point.

With a nominal diameter of 85 mm and thickness of 30 mm, the RPO2840 is designed to provide strong mechanical tightening and effective electrical continuity in professional lightning protection earthing installations. ABB order code 2CTH0RPO2840 and EAN 3660308522818 provide clear identification when specifying replacement components or complete earthing systems.

Reliable Connections for Lightning Protection Earthing

Each down conductor in an external lightning protection system requires connection to an earth termination arrangement capable of dissipating lightning current into the ground. A duck-foot system achieves this by dividing the earthing conductor into multiple strands installed in fan-shaped trenches, increasing the effective contact area with the surrounding soil.

The ABB RPO2840 provides the central connection required to link the branching 30 × 2 mm conductor strips. Its variable strand arrangement makes it suitable for adapting the earth termination geometry to site conditions while maintaining a secure electrical connection between the conductors. It can also be incorporated into systems where the conductor strands terminate at additional earth rods.

Typical Applications

• Duck-foot lightning protection earth termination systems.
• External lightning protection installations.
• Earthing arrangements using 30 × 2 mm tin-plated copper strip.
• Combined duck-foot and earth-rod termination systems.
• Commercial and industrial building lightning protection.
• Infrastructure and utility earthing installations.
