Abstract

This part of IEC 60127 covers requirements for miniature fuse-links for special applications with partial-range breaking capacity. This part of IEC 60127 is applicable to fuse-links with a rated voltage not exceeding 1 000 V, a rated current not exceeding 40 A and a rated breaking capacity not exceeding 50 kA. Miniature fuse-links with partial-range breaking capacity are used only to operate under short circuit conditions. They cannot be applied under overload conditions. This part of IEC 60127 does not apply to fuses completely covered by IEC 60127-7 as well as 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 part of IEC 60127 applies in addition to the requirements of IEC 60127-1. Miniature fuse-links for special applications with partial-range breaking capacity are not intended to be replaced by the end-user of an electrical / electronic appliance. The object of this part of IEC 60127 is to establish uniform test methods for miniature fuse- links for special applications with partial- range breaking capacity, so as to allow verification of the values (for example melting time and breaking capacity values) specified by the manufacturer.
