Scope and object

This standard applies, when required by the relevant product standard, to switchgear and controlgear hereinafter referred to as ²equipment² 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 ²device², 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.
