Alkalmazási terület

This part of IEC 60947 is applicable to the following equipment: – electromechanical contactors and starters including motor protective switching device (MPSD); – actuators of contactor relays; – 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 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: – starters for DC motors 1; NOTE 1 The requirements for DC motor starters are under consideration 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 with additional measure within explosive atmospheres. These are given in IEC 60079 series; – embedded software design rules1; – 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.
