Information × Registration Number 0221U106511, 0121U113414 , R & D reports Title Development by the method of translation and approval by the responsible technical committee of standardization of the national standard harmonized with the international / European (NS-7 Standard) according to the Program of works on national standardization for 2021, namely DSTU EN IEC 60947-9-1 (EN IEC 60947-9 -1: 2019, IDT; IEC 60947-9-1: 2019, IDT) Switching equipment and low-voltage control equipment. Part 9-1. Active protection systems against arc short circuits. Arc extinguishing devices. Development of a national ND to replace DSTU EN IEC 60947-9-1: 2020 (EN IEC 60947-9-1: 2019, IDT; IEC 60947-9-1: 2019, IDT) adopted by the confirmation method popup.stage_title Head Barakhta Yuliia M., Registration Date 09-12-2021 Organization Privately owned enterprise "Electrotechnics-standard" popup.description2  This standard applies to low voltage arc suppression devices designed to eliminate arc short circuits in low voltage complete equipment (usually low voltage complete distribution and control equipment according to IEC 61439 series) by creating a low impedance current path to cause the arc current to switch to a new path. This new current path is maintained until the short-circuit protection device (ACD) interrupts the short-circuit current. PDG is installed in low-voltage complete equipment, connected to the power circuit, preferably as close as possible to all primary power sources. Their rated voltage does not exceed 1,000 V AC or 1,500 V DC. Product Description popup.authors popup.nrat_date 2021-12-09 Close
