60245 IEC 57

What is 60245 IEC 57 cable?

60245 IEC 57: ordinary polychloroprene sheathed flexible cable, 300/500 V. Rating: 300/500 V; 2 to 5 cores, class 5, 0.75 to 4 mm2; IE4 rubber insulation, SE4 polychloroprene (or equivalent) sheath; 60 C (IEC 60245-4 cl. 4, Table 3). Standard: IEC 60245-4 (clause 4); HD 22.4 (HAR H05RN-F).

IEC 60245-4 (standard): an ordinary polychloroprene or equivalent synthetic elastomer sheathed cord; 300/500 V; 2, 3, 4 or 5 class 5 conductors; IE4 rubber insulation; SE4 sheath in one layer; Table 3 has the dimensions of Table 1 (type 53): 0.75 to 4 mm2, mean overall diameter 5.7 to 7.4 mm (2 x 0.75) up to 14.1 to 17.9 mm (5 x 4); 60 C in normal use (4.5). Helukabel's H 05RN-F stops at 1 mm2; the standard runs to 4 mm2. Makers: Helukabel p.12 (manufacturer): Polychloroprene sheathed flexible cable 05RN, H 05RN-F (old NYMHöu), 0,75 and 1 mm2, 300/500 V, HD 22.4 S3, 245 IEC 57. Lapp Japan's CCC list pairs 60245 IEC 57 (YZW) with H05RN-F (search extract). Code designation (IEC 60245-1:2003+A1:2007 Annex A, p. 21 to 22): the first numeral is the basic class (0 non-sheathed for fixed wiring, 5 normal duty flexible, 6 heavy duty flexible, 7 special duty, 8 special application), the second the type within the class, so the number is read whole. The old spelling drops the 60 ('227 IEC 53' = '60227 IEC 53', IEC renumbering); Helukabel's table prints 227 / 245, EN-JV and Top Cable 60227. Core colours (IEC 60245-1:2003+A1:2007 4.1.2, p. 9): one and two cores no preferred scheme; three cores green-and-yellow, blue, brown or brown, black, grey; four cores green-and-yellow, brown, black, grey or blue, brown, black, grey; five cores green-and-yellow, blue, brown, black, grey or blue, brown, black, grey, black; above five cores by colour (green-and-yellow and blue in the outer layer) or by number (4.2). Drawn with the green-and-yellow set when the size says so (3G1.5), otherwise the set without it; two cores are drawn brown and blue (the HD 308 pair, as the standard prefers none); above five cores black numbered cores, the green-and-yellow core last. China: GB/T 5013.4-2008 is an identical adoption (IDT) of IEC 60245-4:2004 (SAMR record, checked 2026-11-09; the portal serves no text of it), so its values are this edition's. JB/T 8735.2-2016 (read in an English translation, site/burn-n18): YZW is YZ with the SE4 sheath (6.6), weather and oil resistant, for outdoor use (3.3), in YZ's sizes (Table 4: 4 and 6 mm2 for 2 to 5 cores, the reduced-core builds, 6 cores 0.75 to 6 mm2); YZWB is the flat one (Table 5).
