TR CU 004/2011 On safety of low-voltage equipment

The technical regulation TR CU 004/2011 On safety of low-voltage equipment represents the minimum safety requirements for electrical equipment in order to protect life, health, property, and environmental as well as protecting consumers against misleading information.

According the Technical Regulation TR CU 004/2011, electrical devices shall be designed and manufactured in such a way that when used as intended they protect against the following:

  • electrocution
  • heat
  • fire
  • mechanical injuries

The products must comply with the requirements of the Technical Regulation TR CU 004/2011 On safety of low-voltage equipment in order to be placed on the Russian and Eurasian market.

Although the requirements of the technical regulation TR CU 004/2011 have been coordinated with the requirements of the Low Voltage Directive 2014/35/EU, they are not identical.

Adopted on August 16, 2011
Came into force on February 15, 2013

As of 15 March 2015, the Technical Regulation TR CU 004/2011 finally definitively abolished the national standards of technical regulation such as GOST or the Russian TR in the territory of the Customs Union.

Application area of TR CU 004/2011 On safety of low-voltage equipment

The Technical Regulation TR CU 004/2011 applies to all low-voltage devices intended for an alternating current of 50 to 1000 volts and a direct current of 75 to 1500 volts.

According to TR CU 004/2011 the following devices are subject to the EAC Certification:

  • household electrical appliances
  • personal electronic data processing machines
  • devices that can be connected to electronic data processing machines
  • electrical tools
  • electronic musical instruments
  • cables
  • automatic and safety switches
  • electrical distribution
  • electrical control units

According to TR CU 004/2011 the following devices are subject to the EAC Declaration:

All low-voltage devices which are not listed in the list of certification-compliant devices are subject to the mandatory EAC Declaration.

According to TR CU 004/2011 a conformity assessment is not necessary for:

  • ATEX equipment
  • medical equipment
  • electrical equipment of elevators
  • military technology
  • control units for electric pasture fences
  • electrical equipment for use in air, water and ground transportation
  • electrical equipment for safety systems of nuclear power plants of reactor plants

It is important to take into consideration that whether or not the devices are subject to conformity assessment according to the TR CU 004/2011, they might be subject to other directives, such as TR EAEU 037/2016 On the restriction of the use of certain hazardous substances in electrical and electronic equipment, TR CU 010/2011 On safety of machinery and equipment or TR CU 020/2011 On electromagnetic compatibility of technical devices.

Conformity assessment process

The conformity assessment with the requirements of the Technical Regulation TR CU 004/2011 On safety of low-voltage equipment occurs in the following forms:

  1. EAC Declaration
  2. EAC Certification

At the request of the manufacturer the EAC declaration can be replaced at by an EAC certification.

EAC marking

TR ZU 004/2011 Über die Sicherheit von Niederspannungsanlagen

The products that have been confirmed to conform with the requirements of TR CU 004/2011 are marked with the EAC sign of the customs union. Placing a product on the market without corresponding marking can be punished with a fine or confiscation.

Period of validity of the EAC certificate

The certificate for serial production is valid for 5 years.

TR CU 004/2011 On safety of low-voltage equipment in the Russian language


We would be pleased to advise you professionally and competently on the EAC certification or declaration. We will verify free of charge whether your products are subject to the conformity certification obligation according to TR CU 004/2011 On safety of low-voltage equipment.

In our video, we explain what an EAC Certification is and how and where to certify or declare your products for the introduction on the EAEU market.

The EAC Certification and the EAC Declaration are complex procedures that attest your products the conformity with the technical regulations of the EAEU and require a lot of know-how. Schmidt & Schmidt will support you with the certification of your products for the EAEU market.

The EAC certificate of the Eurasian Economic Union (EAEU) is an official document, that proofs the conformity of the products with the harmonized technical regulations of the member states of the EAEU. The products, whose conformity with the technical regulations could be confirmed by the certificate of the EAEU, may be moved and sold in the whole customs area of the member states of the EAEU.

The EAC Declaration of the Eurasian Economic Union (EAEU) is an official document that proofs, that the products meet the minimum requirements of the technical regulations of the EAEU. An EAC declaration is issued by the manufacturer, importer or an authorized representative and listed in the official register. Those products, whose conformity with the technical regulations are confirmed by the declaration, have the permission to be freely moved and sold in the whole customs territory of the member states of the EAEU.

The EAC certificate can only be issued after a quality assessment, which has to be carried out by a certification body accredited in one of the member states of the Eurasian Economic Union. The certification is conducted on the basis of technical documentations, company-internal created test reports, or rather test reports provided by accredited test laboratories, as well as on basis of a manufacturing audit on site. The certificate is printed on an official pre-printed form, which has several forgery-proof elements and is authenticated by the signature and seal of an accredited body. The EAC certificate is usually issued for “complex” products that require an extensive control by the authorities.

With the EAC Declaration the manufacturer, importer or authorized representative declares the conformity of his products with the minimum requirements of the technical regulation of the Eurasian Economic Union (EAEU). As distinguished from the EAC certificate, the EAC declaration is issued by the manufacturer or importer himself. All necessary tests and analysis are or made by the manufacturer or in some cases by the laboratory. The applicant issues the EAC declaration himself on a usual piece of paper. The EAC declaration has to be listed in the uniform register of the EAEU by an accredited certification body of one of the member states of the EAEU.
