Control cable BiT 500 (St) CH 3x1.5 SB9803

Control Cable – Reliable Installation and Safety

The BiT 500 (St) 3x1.5 control cable is an advanced solution for electrical installations, designed for demanding applications. This cable combines high manufacturing quality, safety, and functionality, making it an ideal choice for both professional installers and end users. It is suitable for both indoor and outdoor use, ensuring reliable performance under various conditions.

Construction and Properties

The BiT 500 (St) cable features a robust construction. It consists of copper conductors with a cross-section of 1.5 mm², ensuring efficient current transmission. The conductors are insulated with materials meeting high safety standards. Additionally, the cable includes an electromagnetic shield composed of an aluminum foil with a copper braid, minimizing electromagnetic interference and ensuring signal stability. Notably, the cable incorporates an integrated protective earth conductor, enhancing user safety.

A key feature of this cable is its fire resistance—it complies with IEC 60332-1-2 and IEC 60332-3-24 (Category C) standards. It also exhibits low smoke emission in accordance with IEC 61034-2 and achieves a fire reaction class Dca per EN 13501-6. These are critical features for ensuring safety in the event of a fire. The cable is also compliant with halogen-free standards (IEC 60754-1 and IEC 60754-2), meaning it does not release toxic substances during combustion.

Applications and Technical Parameters

The BiT 500 (St) 3x1.5 control cable is widely used in electrical installations for residential, commercial, and industrial buildings. It performs excellently in control systems, automation, and connections of electrical equipment. Its flexibility facilitates installation even in hard-to-reach areas—the minimum bending radius is 77 mm for mobile installations and 38.5 mm for fixed installations. The cable operates at a rated voltage of U/U₀ = 500/300 V and contains three copper conductors with a cross-section of 1.5 mm². The conductors have flexibility class 5. Its outer diameter is approximately 7.7 mm, and the permitted ambient temperature range after installation is from -40°C to +80°C. Conductor resistance at 20°C is 13.3 Ω/km. The cable’s shield consists of aluminum foil reinforced with a copper braid, and the outer sheath is gray. The cable also features smoke emission class s1a, flame-droplet/particle class d2, and acidity class a1.

Thanks to its properties, the BiT 500 (St) cable guarantees safe and reliable operation of electrical installations over a long period. It is an investment in user comfort and peace of mind, as well as assurance of proper system performance for installers.
