This standard applies to semiconductor contactors intended for performing electrical operations by changing the state of electric circuits between on state and off state.<\/p>\n

This standard is additional to IEC Publication 158-1: Low-voltage Controlgear, Part 1: Contactors (including Supplements A and B) which is applicable, provided it is not amended by this standard.<\/p>\n

It applies only to semiconductor contactors, the main circuit of which 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.<\/p>\n

\n

NOTE 1 Semiconductor contactors dealt with in this standard are not intended to provide short-circuit protection of the main circuit, but may contain short-circuit protective devices for semiconductor parts.<\/p>\n

NOTE 2 Semiconductor motor-starters will be dealt with in a later publication.<\/p>\n<\/blockquote>\n

This standard applies also to hybrid-semiconductor contactors, which are also covered by the scope of IEC Publication 158-1 as concerns their electromagnetic part.<\/p>\n

Characteristics, conditions of operation and construction and testing requirements for semiconductor contactors for performing electrical operations by changing the state of electric circuits between on and off states.<\/p>\n","protected":false},"excerpt":{"rendered":"
