Type approval of vacuum interrupter
The vacuum interrupters fitted in the switching devices are type-approved in accordance with
§ 45 of the Radiation Protection Act (StrlSchG) of the Federal Republic of Germany as
interference radiators, and they meet the requirements for interference radiators according to
§ 23 of the latest Radiation Protection Ordinance (StrlSchV) up to the rated voltage specified in
the approval document.
Vacuum interrupters featuring type approval may be operated by the owner of the switchgear
without explicit authorization. The approval document is available on request specifying the
switchgear type and factory reference number.
Electromagnetic compatibility (EMC)
The a.m. standards as well as the "EMC Guide for Switchgear"
[1]
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 fulfil the basic protection
requirements of the EMC guide.
