FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What does 'BN4' signify in the H05BN4-F designation?

Under the CENELEC harmonised designation code, 'B' denotes heat-resistant ethylene-propylene rubber (EI7 EPR) core insulation rated to +90 °C, and 'N4' denotes a heat-resistant chlorosulphonated polyethylene (CSP) or chlorinated elastomer outer sheath (Type EM7) also rated for +90 °C continuous operation.

How does H05BN4-F differ from H05RN-F?

Standard H05RN-F uses EI4/EM2 compounds limited to +60 °C maximum conductor temperature. H05BN4-F uses EI7/EM7 compounds rated for +90 °C continuous conductor operation (+250 °C short-circuit), allowing higher current-carrying capacity and preventing jacket hardening near hot luminaires, boilers and heaters.

When should I choose H05BN4-F versus H07BN4-F?

H05BN4-F is the 300/500 V light-duty cord for 0.75 mm² and 1.0 mm² cross-sections (with 1.5–2.5 mm² extensions). For cross-sections from 1.5 mm² up to 240 mm² or where heavy mechanical impact and 450/750 V (0.6/1 kV protected) ratings are required, select H07BN4-F.

What if my ambient or conductor temperature exceeds +90 °C?

For continuous conductor temperatures up to +110 °C at 300/500 V, select H05GG-F (cross-linked EVA insulation and sheath). For extreme temperatures up to +180 °C, select our Silicone Rubber Multicore High-Temperature Cable.
