Overview
Part 1 of the IEC 60127 standard series covers the general requirements and tests applicable to all types of miniature fuse-links (for example, cartridge fuse-links, sub-miniature fuse-links and universal modular fuse-links) for the protection of electric appliances, electronic equipment and component parts thereof normally intended to be used indoors. Specific details covering each major subdivision are given in subsequent parts. This standard does not apply to fuses for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere. The object of this standard is to establish uniform requirements for miniature fuses so as to protect appliances or parts of appliances in the most suitable way; to define the performance of the fuses, so as to give guidance to designers of electrical appliances and electronic equipment and to ensure replacement of fuse-links by those of similar dimensions and characteristics; to define methods of testing; to define maximum sustained dissipation of fuse-links to ensure good compatibility of stated power acceptance. Fuse links shall be constructed so that their mode of operation is reliable and safe and that their properties are retained with any current up to and including the rated breaking capacity and with any voltage up to the rated voltage if they are used within the limit conditions of this standard. During normal use of the fuse link and within the conditions of this standard, an arc shall not be stopped, nor should sparks or any flames appear on the outside that could endanger the environment. During the test to determine the maximum power loss and after the response, the fuse link shall not exhibit any damage that prevents it from being replaced. The labels must still be legible. Compared to the previous edition, the scope has been expanded to differentiate it from low-voltage electrical systems. Some terms have been revised, new ones have been added. The clause on the endurance test has been changed. 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.
