The Siemens 3TK2806-0BB4 is a high-quality safety contactor designed to enhance the operational integrity of safety circuits. This component is engineered to facilitate enabling and signalling functions within a control system, featuring a configuration of 5 normally open (NO) contacts plus 1 normally closed (NC) contact. It incorporates a self-latching mechanism K1 and operates with a 24 V dc coil, ensuring reliable performance in various industrial applications.
Crafted for seamless integration, the 3TK2806-0BB4 boasts a robust design that can handle solid conductor cross-sections of 1x (4 mm²) or 2x (1 ... 2.5 mm²), as well as finely stranded conductors with core end processing of 2x (0.75 ... 1.5 mm²). It is also compatible with AWG conductors, accommodating solid sizes of 2x (18 ... 14) and stranded sizes of 2x (20 ... 16).
This contactor is specifically tailored for Class A environments, where it excels by minimising radio-frequency interference, although it may require additional measures to mitigate such interference in residential settings. The 3TK2806-0BB4 is not designed for feedback input, start input, or plug-in socket electrical connections, which allows for a more focused application in safety-related circuits.
The product is not associated with position switch monitoring, EMERGENCY-OFF circuit monitoring, valve monitoring, tactile sensor monitoring, or magnetically operated switch monitoring, which underscores its specialised role in safety circuitry. It does not hold certifications such as TÜV, UL approval, or BG BIA certificate, reflecting its specific use-case scenarios.
The Siemens 3TK2806-0BB4 is a testament to Siemens' commitment to quality and reliability, offering a dependable solution for managing safety functions within industrial control systems.
