DIN rail screw terminal SIMBLOCK STB 185-2 - Al/Cu, 87820, blue 81202003

SIMBLOCK busbar connectors – reliable Al/Cu connections

SIMBLOCK STB 185-2 busbar connector is designed for connecting aluminum and copper conductors on TS 35 rails or mounting plates. The connector's design ensures a stable and secure connection, and its versatility allows for use in various electrical installations – from residential construction, through industry, to renewable energy systems. Thanks to the possibility of connecting conductors with a cross-section of up to 185 mm² (solid) and 150 mm² (stranded with ferrule), the connector is suitable for applications requiring high current load.

Construction and application

The STB 185-2 connector is characterized by a solid construction and precise workmanship. Made of high-quality materials, it guarantees durability and resistance to environmental conditions. It has four inputs for conductors with a cross-section of 95-185 mm² (solid) and 70-150 mm² (stranded with ferrule), as well as two outputs for measuring conductors with a cross-section of 1.5-10 mm² (solid) and 1.5-6 mm² (stranded with ferrule). Additional space for a measuring connection facilitates control of the connection status and monitoring of the installation. The use of a dedicated dust cover OSTB 185 provides additional protection against dirt and mechanical damage.
