■ Approval requirements valid in different countries<br />
Siemens low-voltage switchgear and controlgear are designed,<br />
manufactured and tested according to the relevant German<br />
standards (DIN and VDE), IEC publications and European standards<br />
(EN) as well as CSA and UL standards. The standards assigned<br />
to the individual switchgear and controlgear components<br />
are stated in the relevant parts of this catalog.<br />
As far as is economically viable, the requirements of the various<br />
regulations valid - as well as the well-known regulations like VDE<br />
EN and IEC - in other countries are also taken into account in the<br />
design of the equipment in order to be able to supply the devices<br />
worldwide in standard versions.<br />
In some European countries and in North America, an approval<br />
is required for certain low-voltage switchgear and controlgear<br />
components. Depending on the market requirements, these<br />
components have been submitted for approval to the authorized<br />
testing institutes. (see table, page 6/9.)<br />
In some cases, CSA for Canada and UL for the USA only approve<br />
special switchgear designs. For this equipment, partial<br />
limitations of the maximum permissible voltages, currents and<br />
ratings can be imposed, or special approval and, in some<br />
cases, special identification is required.<br />
In some European countries, an approval is required for installation<br />
material. The equipment group „miniature circuit-breakers<br />
and RCCBs“ can still be marked in certain fields and therefore<br />
bears the corresponding marks of approval.<br />
(see table, page 6/9)<br />
For use on board ship, the specifications of the marine classification<br />
societies must be observed. In some cases, they require<br />
type tests of the components to be approved.<br />
