ABB CEF-VT Voltage Transformer Fuses - IEC Standard 7.2kV-24kV

 

ABB medium voltage CEF-VT fuses 7.2kV to 24kV are applicable as voltage transformer fuses and as typical circuit protection requesting current limiting back-up fuses. ABB CEF-VT fuses can be located both inside medium voltage transformer ABB fuse holders and on typical ABB fuse bases.

ABB CEF-VT Voltage Transformer Fuse Features

• MV fuse design for protection against faults in voltage transformer units
• Low minimum breaking current fuses
• Low power losses, specially suitable in enclosed compartments
• High breaking capacity fuse links
• High current limitation
• ABB fuses type tested according to IEC 60282-1
• ABB medium voltage fuses CEF-VT-TCU equipped with Temperature Control Unit, which protects against high temperature in enclosed compartments
• Can be equipped with medium type striker, which is activated immediately when the fuse-elements melt
• HV fuse dimensions according to IEC 60282-1 and DIN 43625
