Threaded busbar connector STB 185 Al/Cu 87810 SIMBLOCK, black 81201007

Universal busbar connector for aluminum and copper conductors

The STB 185 SIMBLOCK busbar connector is a solid and reliable solution for connecting aluminum and copper conductors in electrical installations. The threaded design ensures a secure and durable connection, minimizing the risk of loosening during operation. Thanks to its versatility, the connector is suitable for both new installations and modernization of existing ones.

Construction and application

The connector is designed for mounting on TS 35 rail or directly on a mounting plate. It allows connection of two solid or stranded wires with ferrules with a cross-section from 95 mm² to 185 mm² (for copper conductors) and from 70 mm² to 150 mm² (for aluminum conductors). Additionally, it has a dedicated place for a measuring connection, which facilitates control of installation parameters. This is particularly useful during diagnostics and maintenance.

The STB 185 connector is characterized by high resistance to environmental conditions, and its black color ensures good visibility in poorly lit areas. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.
