Single-core automotive cable FLRY-B 4.0 mm², blue, 50 m spool

Single-core automotive cable FLRY-B 4.0 mm² in blue on a 50 m spool is a flexible low-voltage conductor designed for vehicle electrical installations. The stranded copper core and oil- and heat-resistant PVC insulation make this cable suitable for power distribution, grounding and accessory wiring in cars, trucks, caravans and other road vehicles. Packaged on a compact 50 m spool, the cable is easy to store and unwind for installation, soldering or termination with crimp connectors.

Advantages

The FLRY-B construction provides good flexibility and vibration resistance while maintaining reliable electrical conductivity; the 4.0 mm² conductor cross-section supports moderate current loads typical in automotive circuits. Heat- and oil-resistant insulation ensures long-term performance in engine bays and other areas exposed to oils, fuels or elevated temperatures. The blue color offers clear circuit identification for installation and maintenance, and the spool format simplifies handling and reduces tangling during work.

Suitable for

• Power feeds for lights, pumps and auxiliary devices
• Grounding and chassis connections
• Aftermarket accessories and audio system wiring
• Repairs and rewiring in cars, trucks, motorcycles and caravans

How to use

Plan the routing to avoid sharp edges, hot surfaces and moving parts. Cut the required length from the spool, strip the insulation carefully to expose the stranded conductor, and apply solder or crimp connectors as appropriate for the application. Secure the cable along the vehicle structure with appropriate clamps or ties, and ensure terminals and connections are protected from moisture and contaminants. Verify polarity and continuity before energizing the circuit.

Usage recommendations

Use appropriate fuse protection sized for the expected current load and follow vehicle manufacturer guidelines for wiring routes and attachment points. For installations in high-temperature zones or where additional mechanical protection is required, consider sleeving or conduit. Inspect connections periodically for corrosion or loosening when used in harsh environments.
