Product Description
Dropout Fuses
We are an unparalleled name engaged in offering a wide range of Dropout Fuses. These dropout fuses are designed and developed by our skilled professionals as per the latest technological advancements using supreme class fiber glass tube. This is equipped with heavily tinned non ferrous metal parts at its both ends. The Dropout Fuses are widely used at high-voltage sides as a secondary back-up against faults for protecting the system due to their high efficiency, less maintenance, precise dimensions, sturdy construction and a longer functional life.
Drop Out Fuse (D.O.F) are fuse carriers of fiber glass tube with heavily tinned non ferrous metal parts at both the ends. The brush type phosphorous bronze contacts provide high pressure multi-line connection, wiping and cleaning action. The drop out fuses are widely used for system protection as a secondary back-up against faults or troubles. Installed at high-voltage side, they are able to provide protection in case the trouble is persistent.
