Cutouts, Disconnect Switches, Fuses, Sectionalizers & Reclosers

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. This knowledge comes 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.
