In modern low voltage (LV) distribution networks, the choice of a reliable main to branch mechanical connector plays a critical role in ensuring long‑term system stability, electrical safety, and ease of installation. As utilities continue to upgrade aging infrastructure and contractors work to improve installation efficiency, selecting the right connector becomes increasingly important. Among the most widely recognized and trusted solutions in the industry is the UB1/3 mechanical branch connector, commonly used for connecting LV aluminum and copper conductors in both overhead and underground distribution systems.
The UB1/3 is a mechanical low voltage main branch connector designed to create secure and durable T‑connections within LV distribution networks. It is engineered to accommodate a wide range of conductor sizes and materials, making it suitable for diverse installation environments. One of its most notable features is the use of shear‑head bolts, which ensure that the connector is tightened to the correct torque without requiring specialized tools or torque‑controlled equipment. This design significantly reduces installation errors and enhances consistency across field installations.
Because of its proven performance and widespread adoption, the UB1/3 connector has become a reference model in the industry. As a result, many manufacturers have developed equivalent products that match or exceed the UB1/3 in terms of functionality, mechanical strength, and electrical performance.
Equivalent Models of UB1/3 Mechanical LV Branch Connectors
Jera Line’s CCBI‑S‑2D low voltage mechanical branch connector stands out as a direct functional equivalent to the UB1/3. It offers the same installation convenience and electrical characteristics while providing additional advantages in manufacturing quality, testing rigor, and cost efficiency.
