1.1 General The provisions of the general rules dealt with IEC 60947-1 are applicable to this part of IEC 60947 series where specifically called for. Clauses and subclauses, tables, figures and annexes of the general rules thus applicable are identified by reference to IEC 60947-1:2007, IEC 60947-1:2007/AMD1:2010, and IEC 60947-1:2007/AMD2:2014. EXAMPLE: 4.3.4.1 of IEC 60947-1:2007, Table 4 of IEC 60947-1:2007, or Annex A of IEC 60947-1:2007. 1.2 Scope This document is applicable to the following equipment: – electromechanical contactors and starters including motor protective switching device (MPSD); – actuators of contactor relays and contacts dedicated exclusively to the coil circuit of this contactor or this contactor relay; – dedicated accessories (e.g. dedicated wiring, dedicated latch accessory); intended to be connected to distribution circuits , motors circuits and other load circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c. This document covers also the assessment procedure for electromechanical overload protection used in safety applications: See Annex L. This document does not apply to: – starters for d.c. motors1; NOTE 1 – The requirements for d.c. motor starters are under consider ation for the next maintenance cycle. – auxiliary contacts of contactors and contacts of contactor relays. These are covered by IEC 60947-5-1; – starter used downstream to frequency drive1; NOTE 2 – Additional requirements for starter used downstream to frequency drive are under consideration for the next maintenance cycle. – short-circuit protective device integrated within starters other than MPSDs. This is covered by IEC 60947-2 and IEC 60947-3; – the use of the product within explosive atmospheres. This is covered by IEC 60079 series; – embedded software design rules1; – cyber security aspects. These are covered by IEC 62443 series.
