60245 IEC 53

What is 60245 IEC 53 cable?

60245 IEC 53: ordinary tough rubber sheathed flexible cord, 300/500 V. Rating: 300/500 V; 2 to 5 cores, class 5, 0.75 to 4 mm2; IE4 rubber insulation, SE3 rubber sheath; 60 C (IEC 60245-4 cl. 3, Table 1). Standard: IEC 60245-4 (clause 3); HD 22.4 (HAR H05RR-F).

IEC 60245-4 (standard): 300/500 V; 2, 3, 4 or 5 class 5 conductors (plain or tinned), optional separator; IE4 rubber insulation 0.6 mm (0.75 and 1 mm2) to 1.0 mm (4 mm2), extruded; cores twisted, centre filler allowed; SE3 rubber sheath 0.8 to 1.4 mm in one layer filling the spaces; Table 1: 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 (3.5). The makers read stop at 2.5 mm2; the standard runs to 4 mm2. Makers: Helukabel p.12 (manufacturer): Rubber sheathed flexible cord 05RR, H 05RR-F (old NLH, NMH), 0,75 to 2,5 mm2, 300/500 V, HD 22.4 S3, 245 IEC 53. Lapp Japan's CCC product list pairs 60245 IEC 53 (YZ) with H05RR-F, EN 50525-2-21 and GB/T 5013.4 (read through a search extract; the PDF answered 403). 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): its YZ (IE4 insulation, SE3 sheath, 300/500 V, 60 C; 3.1, 3.2, 6.4, 6.6) has for 2 to 5 cores only 4 and 6 mm2 (Table 4: 2 x 4 to 5 x 6; 5 x 4 mean overall diameter 14.1 to 17.9 mm, as here), the reduced-core 3+1, 3+2 and 4+1 builds and 6 cores 0.75 to 6 mm2: the smaller YZ sizes are this type's (GB/T 5013.4). YZB is the flat one (Table 5: 2 to 6 cores, 0.75 to 6 mm2, cores laid parallel, 6.5).
