Bussmann ABC Series Fast-Acting Ferrule Fuse, Eaton Bussmann Series

Bussmann ABC Series Fast-Acting Ferrule Fuse, Eaton Bussmann Series

The Bussmann ABC Series is a family of fast-acting fuses offered as part of the Eaton Bussmann series, engineered to open a protected circuit quickly when a fault or overcurrent condition occurs. This family is available across a range of amp ratings, including the ABC-20-R, ABC-25-R, ABC-3-R, ABC-5-R, and ABC-6-R models, so contractors and maintenance teams can source the exact rating an original design specified. Unlike time-delay fuse designs that build in an intentional delay to ride through momentary inrush, a fast-acting fuse from the ABC Series responds without delay, making it well suited for protecting sensitive circuits, control components, and equipment that require immediate interruption under abnormal current conditions. Each fuse in the family uses a ferrule connection type for mounting into compatible fuse holders and clips. Because these fuses are manufactured under the Eaton Bussmann series product line, the ABC Series is intended as a straightforward, code-conscious replacement for electrical contractors, maintenance technicians, and facility engineers who need a dependable, drop-in fuse that matches the original protective characteristics of the circuit it serves. Stocking the correct ABC Series fast-acting fuse for a given rating helps ensure continuity of protection when performing scheduled maintenance, troubleshooting a nuisance outage, or completing a panel build where the original design called for a fast-acting Bussmann fuse.

Key Features

• Fast-Acting Response: Opens the circuit rapidly under overload or short-circuit conditions, without the built-in time delay found in time-delay fuse designs.
• Ferrule Connection: Each fuse in the ABC Series uses a ferrule end connection for compatibility with matching fuse holders and clips.
• Eaton Bussmann Series: Manufactured as part of the established Eaton Bussmann series fuse lineup, a widely specified name in commercial, industrial, and electronic circuit protection.
• Multiple Amp Ratings Available: Offered as ABC-20-R, ABC-25-R, ABC-3-R, ABC-5-R, and ABC-6-R models so the correct rating can be matched to the application.
