DESCRIPTION

IEC 60947-4-3:2020

IEC 60947-4-3:2020 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.
