The limits given in this International Standard are applicable to electrical and electronic equipment with a rated input current exceeding 16 A and up to and including 75 A per phase, intended to be connected to public low-voltage a.c. distribution systems of the following types:
31、 nominal voltage up to 240 V, single-phase, two or three wires; nominal voltage up to 690 V, three-phase, three or four wires; nominal frequency 50 Hz or 60 Hz. Other distribution systems are excluded. The limits given in this edition apply to equipment when connected to 230/400 V, 50 Hz systems. Se
32、e also Clause 5. NOTE 1 The limits for the other systems will be added in a future edition of this standard. NOTE 2 Equipment with a rated input current exceeding 75 A per phase should be considered in the harmonic current requirements for installations. See IEC/TR 61000-3-6 and future IEC/TR 61000-
33、3-14. This standard applies to equipment intended to be connected to low-voltage systems interfacing with the public supply at the low-voltage level. It does not apply to equipment intended to be connected only to private low-voltage systems interfacing with the public supply only at the medium- or
34、high-voltage level. NOTE 3 The scope of this standard is limited to equipment connected to public low voltage systems because emissions from equipment installed in private low voltage systems can be controlled in aggregate at the MV point of common coupling using procedures defined in IEC/TR 61000-3
35、-6 and/or by means of contractual agreements between the distribution network operator and the customer. It is expected that operators of private systems will manage the EMC environment in a manner that ensures compliance with the provisions given in IEC/TR 61000-3-6 and/or the contractual agreement

NOTE 5 Professional equipment with input current 16 A per phase and that does not comply with the requirements and limits of standard IEC 61000-3
37、-2 may be permitted to be connected to certain types of low voltage supplies, in the same way as equipment with input current 16 A per phase and that does not comply with the requirements and limits of the present standard (see Annex C). NOTE 6 The limits in this standard are not applicable to stand

Tests according to this International Standard are type tests of complete pieces of equipment. Conformity with this standard can also be determined by validat
