What is this standard about?

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.

This document does not apply to:

  • starters for DC motors;
  • auxiliary contacts of contactors and contacts of contactor relays. These are covered by IEC 60947-5-1;
  • starter used downstream to frequency drive;
  • 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 rules;
  • 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.
