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.
