OBO Bettermann Type 254 Vertical Cross Connector for 8-10mm Round and up to 30x4mm Flat Conductors, Hot-Dip Galvanized Steel 5314038

Unlike generic clamps that force a compromise between round and flat conductor contact, the OBO Bettermann Type 254 vertical cross connector achieves a secure, low-resistance junction between an 8–10 mm round conductor and a flat conductor up to 30 mm wide and 4 mm thick. The screw clamp design applies even pressure across both profiles, preventing the loosening and corrosion that plague lesser connectors in lightning protection and earthing systems.

Highlights

• Hot-dip galvanized steel construction for exceptional corrosion resistance in outdoor and buried applications
• Compatible with round conductors 8–10 mm diameter and flat conductors up to 30 × 4 mm
• Vertical cross configuration allows perpendicular or parallel conductor routing without bending
• Complies with DIN EN 62561-1 (VDE 0185-561-1) for lightning protection components
• High mechanical strength and UV resistance for long-term reliability

In daily use

Installers appreciate the straightforward screw clamp mechanism that requires only a standard wrench. The connector’s geometry keeps conductors aligned and prevents stress on the joint, even under thermal expansion or vibration. Whether used on building facades, industrial plants, or earthing grids, the Type 254 maintains a stable electrical bond with minimal maintenance.
