Test authorities and approval stamps in Europe and North America [t-head1-first]
The standard versions of most Moeller devices are approved for use throughout the world, including the USA and Canada.
Some devices, such as circuit-breakers, are in their basic design usable worldwide with the exception of USA and Canada. For export to North America devices are available with a special UL and CSA approval.
In some cases special country specific installation and operating specifications, installation materials and types must be taken into account as well as special circumstances such as difficult climatic conditions.
Since January 1997 all devices that conform to the European low-voltage guidelines and are for sale in the European Union must be marked with the CE mark.
The CE mark shows that the marked device corresponds with all relevant requirements and standards. This marking duty allows unlimited use of this device within the European economic area.
As devices provided with the CE mark comply with the harmonised standards, approval in the countries of the European Union is unnecessary.
This does not apply to installation material. Additional marking with a national test mark is often required for device groups of miniature and residual current circuit-breakers. The following table shows a selection of test marks.
