Description

Applies to a.c. semiconductor non-motor load controllers and contactors intended for performing electrical operations by changing the state of a.c. electric circuits between the ON-state and the OFF-state. They may include a series mechanical switching device and are intended to be connected to circuits, the rated voltage of which does not exceed 1000 volt a.c. This Standard is identical with and reproduced from IEC 60947-4-3:1999.
