Scope

This part of IEC 60947 is applicable to the following equipment: ?C electromechanical contactors and starters including motor protective switching device (MPSD); ?C actuators of contactor relays; ?C contacts dedicated exclusively to the coil circuit of this contactor or this contactor relay; ?C 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 AC or 1 500 V DC. This document covers also the assessment procedure for electromechanical overload protection used in safety applications such as protecting a motor located in explosive atmosphere from the outside atmosphere: See Annex L. This document does not apply to: ?C starters for DC motors 1; NOTE 1 The requirements for DC motor starters are under consideration for the next maintenance cycle. ?C auxiliary contacts of contactors and contacts of contactor relays. These are covered by IEC 60947-5-1; ?C 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. ?C short-circuit protective device integrated within starters other than MPSDs. This is covered by IEC 60947-2 and IEC 60947-3; ?C the use of the product with additional measure within explosive atmospheres. These are given in IEC 60079 series; ?C embedded software design rules1; ?C cyber security aspects. These are covered by IEC 62443 series. The objective of this document is to state: a) the characteristics of the equipment; b) the conditions applicable to the equipment with reference to: 1) its operation and behaviour@ 2) its dielectric properties@ 3) its degree of protection 4) its construction including safety measures against electric shock@ fire hazard and mechanical hazard; c) the tests intended for confirming that these conditions have been met@ and the methods to be adopted for these tests; d) the information to be given with the equipment or in the manufacturer's literature. 1 For this subject the manufacturer is responsible for taking additional safety measures.
