EN 61000-3-2 Electromagnetic Compatibility (EMC) - Limits - Limits for Harmonic Current Emissions

EN 61000-3-2 deals with the limitation of harmonic currents injected into the public supply system. It specifies the limits of the harmonic components of the input current that can be produced by the equipment under test under specified conditions.

EN 61000-3-2 Electromagnetic Compatibility (EMC) - Limits - Limits for Harmonic Current Emissions

It is applicable to electrical and electronic equipment having an input current of up to and including 16 A per phase and intended for connection to general low voltage distribution systems. This standard includes non-professional arc welding equipment with an input current up to 16 A per phase.

Arc welding equipment for professional use as specified in EN 60974-1 is excluded from this standard and may be subject to installation restrictions specified in EN/TR 61000-3-4 or EN 61000-3-12. The tests performed according to this standard are type tests. Limits have not yet been taken into account for systems with rated voltages less than 220 V (line to neutral).

This edition includes the following important technical changes from the previous edition:

  • Clarifying the repeatability and reproducibility of measurements;
  • More accurate specification of general test conditions for information technology equipment;
  • Adding optional test conditions for information technology equipment with external power supplies or battery chargers;
  • Addition of a simplified test method for equipment subject to minor changes or updates;
  • Updating test conditions for washing machines;
  • Description of Class C equipment requirements with active input power;
  • Updating test conditions for audio amplifiers;
  • Description of test conditions for lamps;
  • Updating test conditions for vacuum cleaners;
  • Adding test conditions for high-pressure cleaners;
  • Updating test conditions for arc welding equipment;
  • Reclassification of variable speed drive refrigerators and freezers to Class D;
  • Addition of test conditions for refrigerators and freezers.
