SIMBLOCK STB 185 - Al/Cu threaded busbar connector, 87810, blue 81201003

SIMBLOCK threaded busbar connectors – a reliable connection point in the installation

SIMBLOCK STB 185 threaded busbar connector is an element dedicated to connecting aluminum and copper wires, providing a safe and durable connection in electrical installations. The connector's design is intended for ease of installation and high reliability, which will be appreciated by both professional installers and end users. Made of high-quality materials, it guarantees connection stability even under high loads.

Versatility and technical parameters

The STB 185 connector is characterized by a wide range of permissible wire cross-sections, making it a universal solution in many applications. The ability to connect stranded and solid wires with ferrules increases installation flexibility. Additionally, the presence of a place for a measuring connection allows easy access to a control point in the circuit. It provides a rated voltage of 1000 V AC/DC, compatible with most standard installations. The rated current for copper wires is 353 A, allowing use in circuits with high current intensity. It accepts solid wires with a cross-section of 2 x (95-185) mm² and stranded wires with ferrules with a cross-section of 2 x (70-150) mm². A dedicated place for a measuring connection allows connecting a solid wire with a cross-section of 1 x (1.5-10) mm² or a stranded wire with a ferrule with a cross-section of 1 x (1.5-6) mm². Mounting is done on a TS 35 rail or mounting plate, ensuring easy and quick installation in standard distribution boards and electrical cabinets.

Work comfort and additional functions

The SIMBLOCK STB 185 connector is equipped with a number of functions that facilitate the work of installers. The available OSTB 185 dust cover provides easy access to the measuring connection, and the solid construction guarantees connection stability even in difficult working conditions. The blue color makes it easier to identify the connector in the installation and allows for visual differentiation of individual circuits. The unique shape of the core and the ribbing of the housing ensure effective heat dissipation, which translates into a longer connection life and minimizes the risk of overheating.
