IEC EN 61000-3-2

IEC 61000-3-2 "Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic current emissions (equipment input current ≤ 16 A per phase)" is an international standard concerning the harmonics emitted by electric equipment.

The analog European standard is called EN 61000-3-2 EN61000-3-2.

Scope

International standard IEC 61000 – 3-2:2006 +A1+A2 is applicable for electrical equipment that is supplied from mains network with voltage not less than 220V and current up to 16A (including) to limit the harmonic component emission.

From the scope of this standard the following equipment are excluded:

• Equipment with rated power less than 75W, except class C equipment
• Professional equipment with power >1 kW
• Symmetrically controlled heating elements with power ≤200W
• Independent dimmers for incandescent luminaries with power ≤1 kW
