Transformer Fuses – MV HV Fuses 2kV-24kV Transformers IEC ABB CEF-VT

ABB CEF-VT transformers fuses are current-limiting fuses which are especially suited for compact MV-HV switchgear and for switch-fuse combinations, 7.2-24kV, 2-6.3A.

MV-HV fuses are suitable for 6.6/7.2kV and up to 24kV transformer applications in accordance with IEC specification.

ABB CEF-VT-TCU transformer fuses have integrated thermal released striker pins allowing the fuse release to be temperature dependant and overload spots which significantly reduce the fuse temperature during the interruption process. The CEF-VT fuse has a high capability up to 63kA and temperature control units increase application safety for gas insulated panels, switchgear and electrical equipment up to 24kV.

CEF-VT current limiting fuses are back-up type medium voltage fuses which limit the value of prospective short-circuit currents during the interruption process and extended the life time of nearby installed electrical equipment. CEF-VT fuses when used in combination with load break switches equipped with fuse tripping system ensures control over the full range of overload and short-circuit currents.
