CEI - EN IEC 60947-4-1

Low-voltage switchgear and controlgear Part 4-1: Contactors and motor-starters - Electromechanical contactors and motor-starters

inactive
Organization: CEI
Publication Date: 1 August 2019
Status: inactive
Page Count: 194
ICS Code (Other electrical accessories): 29.120.99
ICS Code (Low voltage switchgear and controlgear): 29.130.20
scope:

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.

1 For this subject the manufacturer is responsible for taking additional safety measures.
