Overview

This Part 7 of the DIN EN 60127 standard series covers requirements for miniature fuse-links for special applications. Miniature fuse-link for special applications are enclosed fuse-links which are not covered in the scope of IEC 60127-2, IEC 60127-3 or IEC 60127-4 and of rated breaking capacity not exceeding 50 kA, with a width and height not exceeding 12 mm and a length not exceeding 50 mm. It does not apply to fuses completely covered by the subsequent parts of IEC 60269-1. It does not apply to miniature fuse-links for appliances intended to be used under special conditions, such as in corrosive or explosive atmospheres. This standard applies in addition to the requirements of IEC 60127-1. This standard is applicable to fuse-links with a rated voltage not exceeding 1 000 V, a rated current not exceeding 20 A and a rated breaking capacity not exceeding 50 kA. Miniature fuse-links for special applications are not intended to be replaced by the end-user of an electrical / electronic appliance. The object of this standard is to establish uniform test methods for miniature fuse-links for special applications, so as to allow verification of the values (for example melting time and breaking capacity values) specified by the manufacturer. According to the wish expressed by the users of miniature fuses, all standards, recommendations and other documents relating to miniature fuses should 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 facilitates the establishment of new standards, because clauses containing general requirements need not be repeated. The IEC 60127 series, under the general heading "Miniature fuses", is thus subdivided as follows:- IEC 60127-1, Miniature fuses - Part 1: Definitions for miniature fuses and general requirements for miniature fuse-links; - IEC 60127-2, Miniature fuses - Part 2: Cartridge fuse-links; - IEC 60127-3, Miniature fuses - Part 3: Sub-miniature fuse-links; - IEC 60127-4, Miniature fuses - Part 4: Universal modular fuse-links (UMF) - Through-hole and surface mount types; - IEC 60127-5, Miniature fuses - Part 5: Guidelines for quality assessment of miniature fuse links; - IEC 60127-6, Miniature fuses - Part 6: Fuse-holders for miniature fuse-links; - IEC 60127-7, Miniature fuses -Part 7: Miniature fuse-links for special applications; - IEC 60127-10, Miniature fuses - Part 10: User guide for miniature fuses. The responsible committee is DKE/K 663 "Gerätesicherungen (G-sicherungen)" ("Device fuses (miniature fuses)") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
