TR CU 004/2011 Certification Guide

Safety of low-voltage equipment

Overview

This Technical Regulation applies to the certification of low-voltage (LV) equipment, to be operated in Russia and in the common customs territory of the EAEU (EurAsian Economic Union - former Customs Union).

It applies to electrical equipment suitable for connection to the network with a voltage of 75-1500 V (DC) or 50-1000 V (AC), such as control panels, switchboards, electric motors.

It sets the minimum necessary safety requirements for low-voltage equipment to be followed to protect users from injury, electrocution, heat, fire.

The requirements of CU TR 004/2011 have been coordinated with the requirements of the European Low-Voltage Directive LVD 2014/35/EU, although they are not identical.

CU TR 004/2011 does not apply to equipment for use in an explosive atmosphere (in this case CU TR 012/2011 applies).

  • Certificate of Conformity: required for domestic appliances, PC and accessories, electric hand tools, cables, automatic circuit breakers, power distribution switchgear and stand-alone control panels.

  • Declaration of Conformity: required for all other LV equipment.
