Specifications, standards and certifying
Definitions
ABB low voltage devices are developed and manufactured according to the rules set out in IEC international publications and in EN european
specifications.
In most countries, low voltage apparatus is built according to such rules with checking being the responsibility of the manufacturer. The devices
are therefore not subject to any further obligation for approval. A test report from our laboratories can be remitted to our customers, on request,
for presentation to different qualified local organizations.
Prescriptions and standards
International specifications
The International Electrotechnical Commission, IEC, which is part of the International Standards Organization, ISO, publishes IEC publications
which act as a basis for the world market.
European specifications and national specifications
The European Committee for Electrotechnical Standardization (CENELEC), which groups together 18 European countries, publishes EN standards.
These European standards differ very little from IEC international standards and have similar numbering.
The same applies for national standards which use, without exception, the same numbering and reproduce the texts of these unified standards in
their entirety. Contradicting national standards are withdrawn.
European directives
The guarantee of the free movement of goods within the European Community means that any regulatory differences between member states
have been eliminated. The European directives set up common rules that are included in the legislation of each state while contradictory regula-
tions are cancelled.
Three directives are essential:
–– Low voltage directive 2006/95/EC concerns electrical equipment from 0 to 1000 V AC and from 75 to 1500 V DC
–– This specifies that compliance with the requirements that it sets out is acquired if the equipment conforms to the standards harmonized on a
european level: EN 60947-1 and EN 60947-4-1 for contactors
–– Machines directive 2006/42/EC for safety specifications of machines and equipment on complete machines. Machines bearing the ce mark
comply with these specifications
–– E lectromagnetic compatibility directive 2004/108/EC which concerns all devices able to create electromagnetic disturbance
–– S tandard EN 60947-4-1 does not set out any requirement concerning the level of emission or immunity of contactors which do not have any
10 active electronic components. Owing to this fact, compliance with standard EN 60947-4-1 meets the requirements for ce marking, with respect
to this directive.
CE Marking :
–– must not be confused with a quality label
–– is proof of conformity with the European Directives concerning the product
–– is part of an administrative procedure and guarantees free movement of the product within the European Community.
