Description

Brand Name

Bussmann

Type

Type RBA4 Single Barrel Standard Speed

Description

Westinghouse electric company introduced the redesigned and improved RBA (indoor with exhaust control device filter or condenser) and RDB (vented outdoor dropout) ranges of boric acid DE-ION® fuses to replace the BA range of fuses EATON RBA (refillable boric acid) and RDB (refillable dropout boric acid) power fuses are expulsion type power fuses designed for indoor or weatherproof enclosure (RBA) or outdoor vented (RDB) applications. RBA/RDB fuses are renewable (refillable) as the descriptions above state. The whole fuse unit is not discarded after a fault interruption. Usually, only 1-piece of the fuse, the refill unit, needs to be replaced after an interruption and for this reason, RBA/RDB fuses provide an economical approach to the protection of power circuits rated up to a maximum of 38 kV. They are especially well suited for large industrial load fusing needs.
