Control cable BiT 500 (St) CH 21x0,5 SB9720

Control cable BiT 500 (St) CH 21x0.5 – reliability and safety in every circuit.

The BiT 500 (St) CH 21x0.5 control cable is a flexible, multi-core cable designed for control installations inside and outside buildings. Made of copper conductors with a cross-section of 0.5 mm², it provides stable and safe connections in various applications. The cable is characterized by high resistance to external factors and mechanical damage, making it an ideal choice for both professional installers and end users.

Construction and properties

The BiT 500 (St) CH 21x0.5 cable stands out with its advanced construction ensuring optimal operating parameters. It has a screen in the form of an aluminum foil and a copper braid, which effectively protects against electromagnetic interference. The cable conductors are numbered, which facilitates the identification and connection of individual wires. Additionally, the cable is made of halogen-free materials, which increases safety in case of fire – it limits the emission of toxic gases. The fire reaction class is Dca, and the acidity class a1 confirm its high fire protection properties.

• Shielding: Aluminum foil + copper braid – minimizes electromagnetic interference, ensuring stable signal transmission.
• Halogen-free: Reduces the risk of toxic gas formation during a fire, increasing the safety of people and property.
• Conductor numbering: Facilitates identification and connection of wires, reducing installation time and minimizing errors.
• Flexibility: Allows easy routing of the cable in tight spaces and complex installations.
• Weather resistance: Designed for use both indoors and outdoors.
• Rated voltage: 300/500V – universal application in control circuits.
