DIN EN 60127-6:2015-07

This part of IEC 60127 is applicable to fuse-holders for miniature cartridge fuse-links according to IEC 60127-2 and sub-miniature fuse-links according to IEC 60127-3 for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to use indoors. This standard covers requirements, test equipment and test methods for fuse-holders. It is a self-standing document, which refers back to IEC 60127-1 with regard to certain definitions and the atmospheric conditions for test; it also makes reference to other parts of the IEC 60127 series with regard to dimensions and maximum power losses of fuse-links. Features of unexposed or exposed fuse-holders include: - the types of mounting: panel and base mounting, printed circuit board mounting; - the method of fastening on panel: fixing nut fastening (threaded nut); snap-in fastening; - the method of fastening on printed circuit (PC) board: solder fastening, plug-in fastening; - the method of insertion of the fuse-carrier into the fuse base: screw insertion, bayonet insertion, plug-in insertion; - the types of terminals: screw terminals, solder terminals, quick connect terminals, solderless terminals, for example crimp terminal, wire wrap terminal; - the protection against electric shock: fuse-holder without integral protection against electric shock, fuse-holder with integral protection against electric shock, fuse-holder with enhanced integral protection against electric shock. This standard applies to fuse-holders with a maximum rated current of 16 A, a maximum rated voltage of 1 500 V d.c. or 1 000 V a.c. and for use up to 2 000 m above sea-level, unless otherwise specified. The object of this standard is to establish uniform requirements for safety and the assessment of electrical, mechanical, thermal and climatic properties of fuse-holders and the compatibility between fuse-holders and fuse-links. After introductory clauses stipulating the scope and objective, terms and definitions and general requirements, the preferred standard ratings and classifications for fuse-holders, the protection against electric shock, clearances and creepage distances are explained. Additional subjects are the electrical, mechanical and thermal requirements as well as endurance and additional requirements. The annexes contain explanations on the test PC board for fuse-holders of rated currents up to 10 A, the type tests, test sequences, and number of samples as well as the insulation coordination. This edition includes the following significant technical changes with respect to the previous edition: a) modify the arrangement of the fuse-holder samples in the planes; b) add the glow-wire ignition test; c) decrease the maximum gauge size D and increase the minimum gauge size in Table 5. The standards, recommendations and other documents relating to miniature fuses have the same publication number in order to facilitate reference to fuses in other specifications, for example, equipment specifications. Furthermore, a single publication number and subdivision into parts would facilitate the establishment of new standards, because clauses and subclauses containing general requirements need not be repeated. The new IEC 60127 series is thus subdivided as follows: IEC 60127, Miniature fuses (general title) IEC 60127-1, Part 1: Definitions for miniature fuses and general requirements for miniature fuse-links IEC 60127-2, Part 2: Cartridge fuse-links IEC 60127-3, Part 3: Sub-miniature fuse-links IEC 60127-4, Part 4: Universal modular fuse-links (UMF) - Through-hole and surface mount types IEC 60127-5, Part 5: Guidelines for quality assessment of miniature fuse-links IEC 60127-6, Part 6: Fuse-holders for miniature fuse-links IEC 60127-7, Part 7: Miniature fuse-links for special applications IEC 60127-8 (free for further documents) IEC 60127-9 (free for further documents) IEC 60127-10, Part 10: User guide for miniature fuses. The responsible committee is DKE/K 663 "Gerätesicherungen (G-Sicherungen)" ("Equipment fuses") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
