Reely SIFF Silicone Wire 1 x 4 mm² Red 5 m

High-temperature silicone-insulated wire solves the problem of insulation melting or cracking in demanding electrical environments. This red 4 mm² single-core cable withstands temperatures from -60 °C to +180 °C, making it ideal for model making, industrial electronics, and any application where heat resistance and flexibility are critical.

Who is it for

Model builders, hobbyists, and electronics technicians who need a reliable, highly flexible wire that can handle high currents and extreme temperatures without insulation failure.

Main features

• Fine stranded tinned copper conductor for excellent flexibility and corrosion resistance
• Silicone insulation remains flexible even at low temperatures
• Rated for up to 500 V and approximately 40 A current (application dependent)
• Red colour for easy identification in wiring harnesses
