IEC 60269-4:1974 ED1

Low-voltage fuses Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices IEC 60269-4:1974 ED1

Publication date:   Jan 1, 1974

Scope

For application in equipment containing semiconductor devices for circuits up to 1000 V a.c. to circuits of nominal voltages up to 1500 V d.c.
Establishes characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics provided their dimensions are identical. Defines standard conditions for operation in service, characteristics of fuses, markings, standard conditions for construction and tests.
Appendix A provides a guide for the coordination of fuse-links with semiconductor devices.
Note: - To be read in conjunction with IEC 269-1.
