4-hole control joint, wire-rope socket B for up to 50mm (galvanized steel) /OC/ AH03091

Lightning protection system control connector – reliability and safety

This control connector, made of galvanized steel, is designed to connect the lightning protection wire to the conductor plate. It allows for a connection in the range of wires with a diameter of 8 to 10 mm and a conductor plate up to 50 mm. It provides a solid and durable connection, crucial for the proper functioning of the surge protection system. Mounting is done with four M10x20 screws, also galvanized, which guarantees corrosion resistance.

AH Hardt control connectors are not only a connecting element – they are a control point in the lightning protection system. They allow for easy checking of grounding resistance and circuit continuity without the need to disassemble the wires. Thanks to this, the installation inspection becomes faster and less invasive. Mounting the connector in boxes or manholes provides easy access to the control point and protects it from the effects of weather conditions.

Durability confirmed by tests and warranty

The product is distinguished by the highest class of anti-corrosion protection, obtained thanks to a special galvanizing process and sealing the coating with a polymer – confirmed by BBJ-SEP tests. It has also been tested in accordance with the PN-EN 62561-1 standard, obtaining a class H lightning strike current of 100kA, which proves its reliability in extreme conditions.
