Overview
The B3 International C6179 is a latest heavy-duty, armored KNX communication cable designed for secure data transmission in smart building installations. Engineered to withstand mechanical stress, moisture, and environmental interference, this cable is ideal for outdoor, underground, or industrial KNX applications where regular bus cable may be too vulnerable.
The B3 International also have C5974 (2-core) and C5975 (4-core) KNX armoured cables are designed for European Installation Bus (KNX) applications including lighting, blinds, HVAC, and security control. Both variants comply with EN 50290-2 and ISO 4892-3 standards, ensuring reliable system integration with KNX-certified devices. These cables are manufactured for stable data transmission and durability under demanding installation conditions.
Each cable is constructed with solid bare copper conductors of 0.80mm diameter, insulated with polyethylene (PE). The 2-core (C5974) version uses a twisted pair configuration, while the 4-core (C5975) is stranded into a quad formation. A PET foil wrapping combined with a tinned copper drain wire and an aluminum/polyester tape screen provides 100% coverage for enhanced protection against electromagnetic interference (EMI).
Key Features

- Compliance: IEC 61156-1 / KNX TP1 compatible
Pros
- Excellent for outdoor runs, underground ducts, or mechanical risk zones
- Full compliance with KNX TP1 wiring specs
- Halogen-free and flame-retardant—safe for commercial and residential spaces
- Extra mechanical strength extends cable lifespan
- Trusted brand with wide availability in structured cabling networks
Considerations
- Not needed for standard indoor wall runs—adds cost and thickness
- Slightly stiffer than non-armored KNX cable—planning of bend radius required
- May require gland or armored termination accessories at panel entries
Verdict
The B3 C6179 Armored KNX Cable is the go-to choice for projects that demand more than just basic signal transmission. Whether you’re routing through outdoor trenches, industrial risers, or environments prone to interference, this armored cable gives you peace of mind and KNX-compliant performance. A smart investment for professional-grade installations.
⭐ Overall Rating: 4.8 / 5
Excellent for robust KNX wiring in commercial, outdoor, or underground installations.
