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.<\/p>\n
