The H03RN-F is a light-duty heat-resistant rubber flexible cable designed for connection of small household appliances, luminaires, and portable tools at voltages up to 300/300V. Vulcanised natural rubber insulation and sheath deliver excellent flexibility and resistance to deformation, making it ideal wherever a soft, pliable cord is required.
Manufactured to IEC 60245 and harmonised European standard EN 50525-2-21, H03RN-F is available in conductor cross-sections from 0.75 mm² to 1.5 mm² in 2-core and 3-core configurations. The cable is lightweight, UV-tolerant, and suitable for indoor and limited outdoor use in dry or damp environments.

H03RN-F (300/300V) is lighter than H05RN-F (300/500V) or H07RN-F (450/750V). For heavier portable tools, damp environments, or higher voltages, step up to H05RN-F or H07RN-F. Its harmonised designation is accepted across European and international markets without re-approval.
We supply H03RN-F in standard drum lengths (100 m, 500 m) and can accommodate special core counts or cross-sections on request. Contact our sales team for custom configurations.
