Miniature fuses – Part 7: Miniature fuse-links for special applications
|Publication Date:||1 March 2013|
|ICS Code (Fuses and other overcurrent protection devices):||29.120.50|
This part of IEC 60127 covers requirements for miniature fuse-links for special applications.
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 1000 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.
