BS EN 60269-4:2009+A2:2016
This standard BS EN 60269-4:2009+A2:2016 Low-voltage fuses is classified in these ICS categories:
- 29.120.50 Fuses and other overcurrent protection devices
These supplementary requirements apply to fuse-links for application in equipment containing semiconductor devices for circuits of nominal voltages up to 1 000 V a.c. or 1 500 V d.c. and also, in so far as they are applicable, for circuits of higher nominal voltages.
Such fuse-Iinks are commonly referred to as “semiconductor fuse-links”.
In most cases, a part of the associated equipment serves the purpose of a fuse-base. Owing to the great variety of equipment, no general rules can be given; the suitability of the associated equipment to serve as a fuse-base should be subject to agreement between the manufacturer and the user. However, if separate fuse-bases or fuse-holders are used, they should comply with the appropriate requirements of IEC 60269‑1 .
IEC 60269‑6 (Low-voltage fuses – Part 6: Supplementary requirements for fuse-links for the protection of solar photovoltaic energy systems) is dedicated to the protection of solar photovoltaic energy systems.
These fuse-links are intended for use on systems employing the standardized voltages and tolerances of IEC 60038 . Tests carried out on fuse-links in accordance with previous editions of this standard shall remain valid until such time as complimentary equipment has evolved to the standardized voltages and tolerances of IEC 60038 .
The object of these supplementary requirements is to establish the characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics, provided that their dimensions are identical. For this purpose, this standard refers in particular to
-
the following characteristics of fuses:
-
their rated values;
-
their temperature rises in normal service;
-
their power dissipation;
-
their time-current characteristics;
-
their breaking capacity;
-
their cut-off current characteristics and their I 2 t characteristics;
-
their arc voltage characteristics;
-
-
type tests for verification of the characteristics of fuses;
-
the markings on fuses;
-
availability and presentation of technical data (see Annex BB).
