In 1935, Westinghouse introduced the medium voltage boric acid expulsion fuse followed by the medium voltage current limiting fuse. Even today, medium voltage fuses continue to use that core technology....

Fuses General Product Overview Expulsion vs. Current Limiting (Definitions per ANSI C47.40-1993) General Fuse Component Terms An expulsion fuse is a vented fuse in which the expulsion effect of the gases produced by internal arcing, either alone or aided by other mechanisms, results in current interruption. Backup Fuses A fuse capable of interrupting all currents from the maximum rated interrupting current down to the rated minimum interrupting current. A current limiting fuse is a fuse that, when its current responsive element is melted by a current within the fuse’s specified current...

Fuses General Product Overview Disconnect Mounting The disconnect mounting allows the fuse unit to be removed (off load) using an insulated switch stick. The switch stick grabs a pull ring and disconnects the fuse unit that may then be lifted out of its mounting. Dropout Mounting Dropout mountings are used in outdoor applications. The fuse unit is equipped with a mechanical trigger that unlatches the upper contact, allowing the fuse unit to drop out, increasing the dielectric separation, and providing visible indication of a blown fuse. Live Parts Live parts were briefly discussed as part...

Outdoor Applications . . . . . . . . . . . . . . . . . . . . . . . Product Description Eaton’s expulsion fuses use boric acid as the interrupting medium. Under a fault condition, arc heat decomposes the boric acid into water vapor. The water vapor blast de-ionizes the arc path preventing arc re-ignition after a natural current zero. RBA type indoor expulsion fuses must be fitted with a discharge filter or...
