|ICS Code (Switchgear and controlgear):||29.130|
This technical report, which serves as an application guide for the determination of selectivity between over-current protective devices of low-voltage switchgear and controlgear, summarises the definitions of the terminology and provides examples of application.
The following standards for devices are considered in this technical report:
- IEC 60255-3; IEC 60255-6; IEC 60255-8, IEC 60255-12
- IEC 60269-1, IEC 60269-2, IEC 60269-3;IEC 60269-4;
- IEC 60898-1;
- IEC 60947 series;
- IEC 61008-1;
- IEC 61009-1.
This report does not deal with other forms of protection, such as power-reversal protection, directional protection and arc-protection systems.
