CURRENT LIMITING FUSES
The current limiting fuse (center bolt to center bolt terminals) can be used at the transformers exit , by the low tension side (Máximum 600 V.A.C.) over each one of the conductors used as feeders to the distributin panel in combination with the low tension breakers.
The current limiting fuses are manufactured in a conductor range from 2 AWG to 750 M.C.M., at each extreme of the conductor, as to insulate the system in case of failure.
The current limiting fuses allow the required protection to the distribution network in case of failures such as:
- FAILURE GROUNDING
- OVERCHARGES
- NET SHORT CIRCUITS PHASE TO PHASE
