Fuses and Cutouts

ABB is a leading supplier of medium voltage fuses that are 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).

The ABB fuses are designed based on wide application experience coming from designing of 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). This knowledge gives principle for optimal protection arrangement with special attention to safety and reliability.

    New fast acting fuses to protect wind farms with increased capacity

    ABB CEF-S fuses up to 30 / 40.5 kV are designed to achieve the lowest possible breaking current value at 100 ms. This makes them specially suitable for protection of distribution transformers in modern wind farms, where superior performance of fuses is requested. Application of new fuses with Temperature Control Unit inside MV RMU and compact GIS provides additional protection against high temperature in enclosed panel compartments.
