Preface
This is the harmonized ANCE, CSA Group, and UL standard for Low-Voltage Switchgear and Controlgear - Part 1: General rules. It is the second edition of NMX-J-515-ANCE, the second edition of CAN/CSA-C22.2 No. 60947-1, and the fifth edition of UL 60947-1. This edition of NMX-J-515-ANCE cancels the previous edition published in 2007. This edition of CAN/CSA-C22.2 No. 60947-1 supersedes the previous edition published in 2007. This edition of UL 60947-1 supersedes the previous edition published in 2007. This standard is based on publication IEC 60947-1, fifth Edition (2007).
Scope and object
This standard applies, when required by the relevant product standard to switchgear and controlgear hereinafter referred to as equipment and intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.
It does not apply to low-voltage switchgear and controlgear assemblies which are dealt with in IEC 60439.
NOTE - In certain clauses or subclauses of this standard, the equipment covered by this standard is also referred to as device, to be consistent with the text of such clauses or subclauses.
The object of this standard is to state those general rules and requirements which are common to low-voltage equipment as defined in 1.1, including for example:
- definitions;
- characteristics;
- information supplied with the equipment;
- normal service, mounting and transport conditions;
- constructional and performance requirements;
- verification of characteristics and performance.
Digital inputs and/or digital outputs contained in switchgear and controlgear, and intended to be compatible with programmable controllers (PLCs) are covered by Annex S.
1.1DV.1 D2 Modification to 1.1 by adding the following:
1.1DV.1.1 This equipment is intended for installation in accordance with the national installation codes for use in ordinary locations. See Annex DVB, Table DVB.3, Ref. No. 14.
1.1DV.1.2 IEC 60947-2: Part 2: Circuit-breakers does not apply. They are covered in Annex DVB, Table DVB.3, Ref. No. 3.
1.1DV.1.3 IEC 60947-3: Part 3: Switches, disconnectors, switch-disconnectors and fuse combination units do not apply. They are covered in Annex DVB, Table DVB.3, Ref. No. 1.
1.1DV.2 DR Modification to 1.1 by adding 1.1DV.2.1 and 1.1DV.2.2:
1.1DV.2.1 In Mexico and the United States with respect to the national installation codes, equipment operating at 600 V and less is considered low-voltage equipment. in Canada, with respect to the national installation codes, equipment operating at more than 750 V is considered high voltage equipment.
1.1DV.2.2 Enclosed equipment intended for use as service equipment is to comply with the applicable requirements in this standard and with Annex DVB, Table DVB.3, Ref. No. 7.
In Mexico, this requirement does not apply.
