Eaton’s BA/DBA Power Fuses are medium voltage boric acid expulsion fuses that offer double protection for circuits and equipment which operate on voltages from 7.2 to 145 kV. They carry the boric acid principle of circuit protection to higher voltage ratings, and at the same time provide at lower cost short-circuit protection for systems of moderate capacity. They are available as replacement fuse units for existing applications. The BA fuse units have been replaced by the RBA/RDB fuse units but are not interchangeable.

Eaton’s DBU Power Fuses are boric acid, expulsion-style fuse units suitable for both indoor and outdoor applications. They offer effective protection for electric utility and industrial distribution systems and are designed for use on transformers, feeders, and switchgear. Ideal for higher voltage (up to 38 kV) and high current applications (up to 200A). They are low initial cost alternatives to refillable Boric Acid fuses. The DBU fuses are totally interchangeable with S&C SMU-20 style fuses.

Eaton’s RBA and RDB expulsion power fuse units offer outstanding protection and reliability, broad selection possibilities, ease of installation, and economy over time. They can be used in enclosures (RBA) or outdoors (RDB) for distribution system protection up to an operational voltage of 34.5 kV. The fuses operate exactly when and how they should, and do not operate when they shouldn’t, a subtle but important distinction. The RBA/RDB are a smart alternative to S&C SM4 and SM5 fuse units.
