Why Choose the ABB 2CTH0CRH4020 Earth Rod Clamp?
The ABB 2CTH0CRH4020 is a purpose-designed earth rod clamp for connecting a flat earthing conductor to an earth rod within external lightning protection and earthing systems. Part of ABB’s range of lightning protection accessories, it provides the mechanical and electrical connection required between the earth electrode and the associated earthing conductor.
The clamp is designed for 15–20 mm diameter earth rods and accepts 30 × 2 mm flat tape. This makes it suitable for ABB earthing arrangements where lightning current must be transferred effectively from the down-conductor system into the earth termination network.
ABB identifies the 2CTH0CRH4020 as type CRH4020, with EAN 3660308522160 and an individual weight of approximately 0.15 kg. The product is listed within ABB’s external lightning protection range and is associated with IEC/EN 62561-1 requirements for lightning protection system connection components.

Reliable Connection for Lightning Protection Earthing
An effective external lightning protection system requires each down conductor to be connected to an earth termination system capable of safely dispersing lightning current into the ground. Earth rod clamps provide the critical connection between the buried earth electrode and the conductor forming the wider earthing network.
The ABB 2CTH0CRH4020 is specifically configured to connect 30 × 2 mm flat tape to compatible 15–20 mm earth rods. Its dedicated rod-to-tape design makes it suitable for building and infrastructure lightning protection installations where reliable electrical continuity throughout the earth termination system is essential.
Typical Applications
- External lightning protection systems.
- Earth termination networks.
- Connection of flat earthing tape to earth rods.
- Commercial and industrial building earthing systems.
- Lightning protection installations for infrastructure and utilities.
- Industrial plants and manufacturing facilities.
