Scope

IEC 60947-4-3:2020(E) applies to semiconductor controllers and semiconductor contactors for non-motor load intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V AC.

It covers their use:

– for operations of changing the state of AC electric circuits between the ON-state and the OFF-state;

– with or without bypass switching devices;

– as controller, for reducing the amplitude of the RMS AC voltage.

This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) scope exclusions;

b) editorial correction of notes and hanging paragraphs;

c) safety aspects related to:

- general aspects;

- limited energy circuits;

- electronic circuits;

d) mention of dedicated wiring accessories;

e) power consumption measurement;

f) alignment to IEC 60947-1:2020;

g) alignment with IEC 60947-4-2 when appropriate.
