SIMBLOCK STB 185 threaded busbar connector - Al/Cu, 87810, grey 81201002

Rail-mounted threaded connectors – reliable connections in electrical installations

The SIMBLOCK STB 185 threaded rail connector is an element designed for connecting aluminum and copper wires on TS 35 rails. It enables safe and durable connections in distribution boards, control cabinets, and in building and industrial installations. The connector's design is intended for easy assembly and disassembly, as well as to ensure optimal electrical contact.

Construction and application

The STB 185 connector is characterized by a solid construction and high quality of workmanship. Made of durable materials, it ensures reliable operation even in harsh operating conditions. An additional space for a measuring connection facilitates control of the connection status and monitoring of the installation. The dedicated OSTB 185 dust cap protects the measuring connection from dirt, ensuring easy access to it when needed.

The connector is compatible with both solid wires and stranded wires with ferrules, which increases its versatility. It can be used to connect wires with cross-sections from 95 mm² to 185 mm² (solid wire) and from 70 mm² to 150 mm² (stranded wire with ferrule). The measuring connection accepts wires with a cross-section from 1.5 mm² to 10 mm² (solid wire) and from 1.5 mm² to 6 mm² (stranded wire with ferrule). The single-pole design makes it ideal for creating various connection configurations.
