Bussmann MDA Series Time-Delay Fuse, Ferrule Connection

Bussmann MDA Series Time-Delay Fuse, Eaton Bussmann Series

The Bussmann MDA Series is a family of time-delay fuses manufactured under the Eaton Bussmann series brand, available across amp ratings including MDA-1-R, MDA-2-R, MDA-3-R, MDA-8-R, MDA-12-R, and MDA-15-R to support a range of low-amperage electronic and control-circuit protection needs. As time-delay (slow-blow) fuses, MDA Series fuses are engineered to tolerate brief, harmless current surges, such as motor inrush, transformer energization, or other temporary overload events, while still opening reliably when a sustained overcurrent or fault condition develops. Every fuse in the MDA Series uses a ferrule connection and end type, making them well suited for compact electronic assemblies and control panels that specify ferrule-style fuse holders. This balance of surge tolerance and dependable interruption makes the MDA Series a practical choice for circuits where momentary current spikes are normal but sustained overcurrent must be cleared quickly to protect wiring, components, and connected equipment. As part of the Eaton Bussmann series lineup, the MDA Series is manufactured to support consistent, code-compliant circuit protection practices in commercial, industrial, and OEM electrical systems.

Key Features

• Series: MDA Series fuses from the Eaton Bussmann series product line, available in amp ratings from MDA-1-R through MDA-15-R.
• Time-Delay Operation: Engineered as time-delay (slow-blow) fuses, allowing momentary current surges such as motor inrush or transformer energization without needlessly opening the circuit.
• Overcurrent Protection: Opens the circuit reliably when sustained overcurrent conditions occur, helping safeguard connected equipment and wiring.
• Ferrule Connection: Every option in the MDA Series uses a ferrule connection and ferrule end type, suited to standard ferrule fuse holders and blocks.
