H05RN-F 300/500V TS EN 50525-2-21 Cable

H05RN-F Flexible Rubber Cable — 300/500V (EN 50525-2-21)

H05RN-F is a medium-duty flexible rubber cable rated at 300/500V for use with portable tools, garden appliances, and general-purpose extension leads. Fine-wire annealed copper conductors individually insulated with vulcanised rubber and sheathed in robust neoprene compound deliver excellent flexibility across a wide temperature range.

Compliant with EN 50525-2-21, H05RN-F serves indoor and outdoor environments where a robust flexible connection is required. Multi-core variants (2 to 5 cores) and conductor cross-sections from 0.75 mm² to 6 mm² cover a broad range of load requirements.

Key Design Features

• Class 5 fine-wire annealed copper conductors for high flexibility
• Vulcanised natural or synthetic rubber insulation (05RN type)
• Neoprene outer sheath — oil, ozone, and UV resistant
• Rated voltage 300/500V; temperature range ‑25°C to +60°C
• 2, 3, 4, 5 cores; 0.75 to 6.0 mm²
• Resistant to mechanical abrasion and surface contact with oils
• Harmonised designation for seamless EU market acceptance
• Colour-coded cores per IEC 60446

Selection Guide

H05RN-F vs H07RN-F

H05RN-F (300/500V) suits most portable tools and light-industrial applications. For heavier machinery, outdoor construction sites, or higher voltages (up to 450/750V), choose H07RN-F with its thicker sheath and higher voltage rating.

Choosing Cross-Section

1.5 mm² for loads up to 16 A over short runs; 2.5 mm² for 20 A; 4 mm² for 25 A. Our technical team can assist with precise sizing calculations.
