The vacuum interrupters fitted in the vacuum circuit-breakers are type-approved in
accordance with the X-ray regulations of the Federal Republic of Germany. They conform to
the requirements of the X-ray regulations of January 8, 1987 (Federal Law Gazette I 1987,
Page 114) in the new edition of April 30, 2003 (Federal Law Gazette I 2003, No. 17)
up to the value of the rated voltage stipulated in accordance with IEC/DIN VDE.
The a.m. standards as well as the "EMC Guide for Switchgear"* are applied during design,
manufacture and erection of the switchgear. Installation, connection and maintenance have
to be performed in accordance with the stipulations of the operating instructions.
For operation, the legal stipulations applicable at the place of installation have to be observed
additionally. In this way, the switchgear assemblies of this type series fulfill the basic
protection requirements of the EMC guide.
The switchgear operator / owner must keep the technical documents supplied with
the switchgear throughout the entire service life, and keep them up-to-date in case of
modifications of the switchgear.
* (Dr. Bernd Jäkel, Ansgar Müller; Medium-Voltage Systems - EMC Guide for Switchgear;
A&D ATS SR/PTD M SP)
The fixed-mounted circuit-breaker switchgear of the series 8DB10 fulfills the following degrees
of protection according to IEC 60 529:
• IP65 standard for parts under high voltage
• IP3XD standard for external enclosure
• IP31D option standard for external enclosure
According to "Annex A of the European Agreement Concerning the International Carriage of
Dangerous Goods by Road (ADR)", Siemens gas-insulated medium-voltage switchgear does
not belong to the category of dangerous goods in respect of transportation, and is exempted
from special transport regulations according to ADR, Clause 1.1.3.1 b).
