OBO Bettermann 219 16 SET V4A aardpen-set standaard 4x1.25m 5000720

For earthing and lightning protection systems in aggressive soil conditions, this sectional earth rod set from OBO Bettermann delivers exceptional corrosion resistance and modular flexibility. Unlike standard galvanized rods, the V4A stainless steel construction (1.4571 / AISI 316Ti equivalent) withstands chemical attack and ensures a service life measured in decades. The set includes four 1.25 m rod sections, three couplings, a driving head, and a penetrating tip, allowing a total driven depth of 5 m without welding or special tools.

Highlights

• Complete modular set for immediate installation
• V4A stainless steel rods, couplings, and tip for maximum corrosion resistance
• M16 screw thread connections for secure, low-resistance joints
• Galvanized steel driving head protects rod ends during installation
• Complies with DIN EN 62561-2 (VDE 0185-561-2)
• Extendable design for deeper earthing requirements

In daily use

Installers appreciate the straightforward driving process: screw the tip onto the first section, attach the driving head, and drive the rod into the ground using a standard hammer or power driver. Additional sections are added via the couplings as depth increases. The 16 mm diameter provides a balance of mechanical strength and soil displacement, while the V4A material eliminates the need for cathodic protection or periodic replacement in most soils. This set is ideal for building earthing, lightning protection down conductors, and industrial grounding grids.
