ABB Medium Voltage MV Fuses (Outdoor)

ABB MV / HV Electrical Equipment

Outdoor Fuses for MV Medium Voltage Cable Networks

IEC Outdoor Transformer Fuse CEF

The low power losses for ABB medium voltage fuse links specially suitable in compact switchgear and for fuse switch disconectors combination. ABB CEF medium voltage fuses current limiting are of back-up type. They have a zone between the minimum melting current and the minimum breaking current where the fuse links may fail to interrupt and this zone is very narrow. Low minimum breaking current, low power losses, low arc-voltage and a high breaking capacity and a high current limitation.

ABB Fuses for MV HV Medium & High Voltage Cables & Systems

ABB are a leading manufacturer of medium voltage (MV) fuses used as main or back up protection elements of systems and apparatus. Fuses (commonly recognized as High Voltage Fuses) are classified as current limiting and non-current limiting (expulsion).

ABB fuses are designed based on wide application experience coming from designing of electrical protection in medium voltage systems and coordination with ABB products where fuses are applicable (air and SF6 insulated switchgears with load break switches, distribution transformers and contactors).

ABB MV HV medium-high voltage fuses protect distribution transformers, motors, switchgear and capacitor banks against overload currents - ABB MV-HV fuses can operate as sole devices or can be combined with air/SF6 insulated switch disconnectors. T&D distribute ABB medium voltage fuses for safe protection of 3.3kV, 6.6kV, 7.2kV, 11kV, 12kV 15kV, 20kV, 22kV, 24kV, 33kV, 36kV and 42kV cable systems.
