The ABB 1SBN071303T1000, type LY16-4, is an insulated connecting strip accessory designed for ABB AF09–AF16 three-pole contactors. It provides flexible pole connection options for industrial switching applications, allowing contactor poles to be connected in parallel or series depending on the required electrical configuration.
The LY16-4 connecting strip can be used to create a star point by connecting three poles in parallel, increase AC load capability by paralleling poles, or connect poles in series to increase the DC voltage controlled by the contactor poles. The strip includes secable sections to support different connection arrangements.
With its compact insulated construction and compatibility with ABB AF09, AF12 and AF16 contactors, the LY16-4 provides a practical solution for adapting contactor configurations in industrial motor control and automation systems.

Flexible Contactor Connection for Industrial Systems
Connecting strips such as the ABB LY16-4 allow engineers to adapt standard contactors for specialised electrical configurations. By changing the way contactor poles are interconnected, systems can achieve different current handling or DC switching requirements without replacing the contactor assembly.
The LY16-4 is designed as an accessory for ABB AF contactors, providing a compact and reliable method of configuring parallel or series pole connections in industrial automation, motor control and electrical switching applications.
