Approvals for switching and protective devices

or for power distribution systems are national,

regional or application-specific approvals for the

use of these products

¢ Additional tests by independent and

nationally approved test bodies are often

required and some approvals require the

regular production monitoring by the approval

authority

¢ Approvals often require mandatory marking

on the approved products

© Some approvals require the modification of

the permissible technical data of the approved

products

At present, application restrictions apply to

the approved products

© The flexibility of the manufacturer is restricted

by the fact that each product modification has

to be approved

Further information is provided in the Main

Catalogue for Industrial Switchgear, in the

chapter “Approvals for the World Market”

A check list may help to clarify important questions and take them into account at the quotation stage After a system is completed, any special requirements that were not taken

into account in the engineering stage may

require a high level of cost and time for their implementation

Special characteristics for the export to

North America (USA, Canada) What has become well-established worldwide is not necessarily also acceptable in North America The following should be taken into account for exports to North America:

© North American approvals,

© North American product and installation

standards,

Special market practices,

© Approval by local inspectors

(AHJ = Authority Having Jurisdiction)

North American practices unknown in the IEC world:

© Device types and main applications, Product-specific differences in the scope of the approval,

e Restrictions according to network types,

¢ Application-related differences in device selection

Device types in North America

In North America a distinction is made between

devices for energy distribution, such as in

compliance with UL 489 and industrial

switchgear in compliance with UL 508

UL 489 and CSA-C22.2 No 5-02 stipulate larger

clearance and creepage distances than the IEC

standards and the relevant harmonised

European standards

This affects, for example, the European motor-

protective circuit breaker, which now has

additional terminals on the incoming side to

provide the required clearance and creepage

Industrial control equipment

UL 508 and CSA-C22.2 No 14

Motor starters must only switch and protect motors

© Small clearance and creepage distances are sufficient for motor starters on busbar adapters in the branch circuit"),

Test authorities and approval stamps

Test authorities and approval stamps in Europe and North America

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
