Universal branch connection 57 OC 91400101

Universal branch connector for lightning protection systems

This universal branch connector 57 OC, manufactured by ELKO-BIS, is a key element in the construction and maintenance of lightning protection systems. It is used to connect lightning protection conductors – both wire and tape – at branch and through-connection points. Its design allows for the creation of solid and durable connections, ensuring effective protection against the effects of atmospheric discharges.

The connector is made of galvanized steel, which guarantees corrosion resistance and long-term use even in harsh weather conditions. Screw mounting with a hexagonal screw ensures stability and ease of installation.

Features and application

The 57 OC connector is particularly useful during the construction of lightning protection systems on roofs, facades and other structures exposed to lightning strikes. Its versatility means it can be used in both new installations and in the modernization of existing ones. Thanks to the possibility of connecting conductors of different diameters (wire with a diameter of 8 mm and tape with a width of 25-30 mm), it provides flexibility in the design and installation of the system.

• Solid construction: Made of steel ensures mechanical strength and resistance to damage.
• Corrosion resistance: Galvanic zinc coating protects against the effects of atmospheric factors, extending the life of the connector.
• Versatility: The ability to connect wire (8 mm) and tape (25-30 mm) increases the range of applications.
• Easy installation: Hexagonal screw facilitates quick and secure mounting of the connector.
• High current strength: Maximum surge current up to 100 kA ensures effective protection of the installation during atmospheric discharges.

User parameters and safety

The 57 OC connector has been designed with safety and reliability in mind. Its design allows for the safe discharge of lightning current to the ground, minimizing the risk of damage to the electrical installation and the threat to people. The maximum surge current value (100 kA) demonstrates high effectiveness in protecting against the effects of atmospheric discharges. The use of appropriate materials and precise workmanship guarantee long-term and trouble-free operation of the connector.
