Scope

This document specifies the technical requirements, type tests, and information provided to users for fuse elements of high-voltage fuses used in motor circuits. This document is primarily applicable to fuse elements of fuses used for directly starting motors in AC systems with voltages of 3 kV and above and frequencies of 50 Hz. Note: When the motor used has auxiliary starting, this document is also applicable, but attention should be paid to the selection of the rated current of the fuse, as described in IEC TR 62655:2013, 5.2.3, and consult with the manufacturer of the fuse elements. Fuse elements that comply with this document are suitable for IEC 602821 and are designed to withstand normal operating conditions and motor starting pulses.
