Bussmann SA-30 Type S Fuse Adapter, Edison Base, 30A, 125V

Bussmann SA-30 Type S Fuse Adapter, Edison Base, 30A, 125V

The Bussmann SA-30 is an Eaton Bussmann series SA plug fuse adapter engineered for industrial/commercial grade overcurrent protection applications. Rated 30 A at 125V, this Edison-base adapter installs into a standard Edison-base fuse socket and converts it to accept Type S (rejection-base) fuses, permanently restricting the socket so only fuses rated from S-30 down to S-20 can be inserted. This design helps prevent the use of oversized, mismatched fuses in existing Edison-base fuse panels, supporting safer, properly coordinated branch-circuit protection.

Key Features

• Amperage Rating: 30 A adapter sets the maximum fuse size permitted at the socket once installed.
• Voltage Rating: 125V rating for standard residential and commercial branch-circuit fuse panels.
• Edison Base: Threads into a standard Edison-base fuse socket, converting it to a Type S rejection-base configuration.
• Fuse Compatibility: Designed for use with S-30 down to S-20 Type S fuses, blocking installation of higher-amperage fuses that could overload branch-circuit wiring.
• Industrial/Commercial Grade: Built for demanding industrial and commercial electrical environments requiring dependable overcurrent protection.
• Series: Part of the Eaton Bussmann SA series plug fuse adapter line.
