4-hole control connector, wire-bednarka B for 40mm (copper) /CU/ AH03052

Control connector for connecting lightning protection wire to the earthing busbar

This control connector, made of copper, is designed to connect lightning protection wire to the earthing busbar. It allows for a connection within a range of wire diameters from 8 to 10 mm and a busbar up to 40 mm. It is a key element of the lightning protection system, allowing for regular checks of the earthing resistance without the need to disassemble the wires. This ensures the continuity and reliability of the system protecting against atmospheric discharges.

Construction and application

The connector consists of a copper housing and four M8x16 screws made of brass. The brass screws provide good electrical conductivity and corrosion resistance, which translates into a long-lasting and stable connection. The design with four holes allows for secure fastening of both the wire and the busbar.

AH Hardt control connectors are used in:

• Lightning protection installations of buildings and industrial facilities
• Lightning protection boxes and manholes – facilitate access to the control point
• Earthing systems requiring regular resistance measurements
• Mounting at a height of about 1 meter above the ground – provides easy access for inspection and minimizes the impact of weather conditions.

Features and benefits

• High purity copper (99.99%) – guarantees excellent electrical conductivity and corrosion resistance, which translates into long-term operation of the installation.
• Brass M8x16 screws – ensure a stable connection and resistance to weather conditions.
• Complies with PN-EN 62561-1 standard – confirms the safety and reliability of the product.
• Allows measurement of earthing resistance – without the need to disassemble the wires, saving time and costs.
• Easy installation – thanks to standard screw and mounting hole dimensions.
• Durable construction - ensures years of operation without the need for replacement.
