2.7.1.2 - UR fuse, line reactor and RFI filter options
• UR fuses
Ultra-fast fuses provide very effective protection against the effects of short circuits.
They ensure the protection of power semiconductors by having a much lower fuse melting time than aM or Gg fuses.
• RFI filters:
The use of RFI filters helps to reduce the level of emission of radiated and conducted radio frequency signals. They enable
MD3REC components to comply with the EN61800-3 standard on variable speed drives. The Powerdrive MD Smart rectifiers have
been tested with Schaffner filters. The following tables show the compliance levels achieved and the types of filters used.

CAUTION
The specific design of these filters makes it possible to use them in installations with an IT neutral system. However,
the installer shall ensure that the isolation control systems dedicated to these installations are suitable for monitoring
electrical equipment that may incorporate electronic variable speed drives.
• Line reactors:
The line reactor is a filtering element to limit the disturbance of the electrical network.
