High voltage current limiting back-up fuses are protection elements that are widely employed in MV systems to protect overhead lines, power cables, motors, transformers, capacitor banks, disconnectors and switches against short-circuit currents over rated values.
High voltage current limiting back-up fuses that we are introducing here efficiently limit the current that flows through the circuit. This means that, because of its very quick operation under certain values of the short-circuit current, the fusion prevents the first halfwave of the short circuit from reaching its corresponding maximum value.

Protection of medium voltage switchgear against short circuit and fault currents by fuses is an excellent solution due to their low cost and maintenace free requirements.

Güral current limiting back-up fuses have excellent capability of breaking, under specific conditions of use and behaviour, all currents from the rated maximum breaking current down to the rated minimum breaking current.
We offer our Clients an extensive range of HV current limiting back-up fuses with system voltages from  7.2 kV to 36kV and rated currents from 2 A to 250 A.
