The degree of conformity is identical (IDT). The method of acceptance is translation. The national standard was developed to replace DSTU EN IEC 60947-3:2022 (EN IEC 60947-3:2021, IDT; IEC 60947-3:2020, IDT), adopted by the confirmation method. This standard applies to switches, disconnectors, switch-disconnectors and their combinations with fuses, as well as their special accessories used in power distribution circuits and electric motor circuits, the rated voltage of which does not exceed 1 000 V a.c. current or 1500 V direct current. This standard establishes: a) equipment characteristics; b) conditions applicable to equipment with reference to: 1) operation and behavior during normal maintenance; 2) operation and behavior in case of defined abnormal conditions, for example short circuit; 3) dielectric properties; c) tests to confirm compliance with these conditions and the methods adopted for these tests; d) information regarding the marking of the equipment or provided by the manufacturer, for example in a catalog.
