Miniature fuses – Part 7: Miniature fuse-links for special applications
|1 September 2015
|ICS Code (Fuses and other overcurrent protection devices):
This part of IEC 60127 covers requirements for miniature fuse-links for special applications.
This part of IEC 60127 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.
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 part of IEC 60127 applies in addition to the requirements of IEC 60127-1.
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 part of IEC 60127 is to establish uniform test methods for miniature fuselinks for special applications, so as to allow verification of the values (for example melting time and breaking capacity values) specified by the manufacturer.
