标准摘要
Applies to semiconductor contactors intended for performing electrical operations by changing the state of electric circuits between on state and off state. The main circuit of the semiconductor contactors is intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.
