Thermal-links. Requirements and application guide (IEC 60691:2023)

Alkalmazási terület

This International Standard is applicable to thermal-links intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions. NOTE 1 The equipment is not designed to generate heat. NOTE 2 The effectiveness of the protection against excessive temperatures logically depends upon the position and method of mounting of the thermal-link, as well as upon the current which it is carrying. This document may be applicable to thermal-links for use under conditions other than indoors, provided that the climatic and other circumstances in the immediate surroundings of such thermal-links are comparable with those in this standard. This document may be applicable to thermal-links in their simplest forms (e.g. melting strips or wires), provided that molten materials expelled during function cannot adversely interfere with the safe use of the equipment, especially in the case of hand-held or portable equipment, irrespective of its position. Annex H of this document is applicable to thermal-link packaged assemblies where the thermallink( s) has already been approved to this standard but packaged in a metallic or non-metallic housing and provided with terminals/wiring leads. This document is applicable to thermal-links with a rated voltage not exceeding 690 V AC or DC and a rated current not exceeding 63 A. The objectives of this document are: a) to establish uniform requirements for thermal-links, b) to define methods of test, and c) to provide useful information for the application of thermal-links in equipment. This document is not applicable to thermal-links used under extreme conditions such as corrosive or explosive atmospheres. This document is not applicable to thermal-links to be used in circuits on AC with a frequency lower than 45 Hz or higher than 62 Hz.
