| Predmet normy: | 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. |
