Bussmann FWA-25A10F High-Speed Semiconductor Fuse, 500V, 25A, Ferrule End

Bussmann FWA Series High-Speed Semiconductor Fuse

Bussmann FWA Series high-speed fuses from Eaton Bussmann provide fast-acting, non-indicating overcurrent protection engineered specifically for semiconductor and power electronic circuits. Rated 500V with a 25A capacity and a 100 kAIC interrupt rating, this fuse features a ferrule end x ferrule end termination style designed for rapid current interruption under fault conditions. High-speed fuses like this Eaton Bussmann FWA series fuse are essential for protecting sensitive semiconductor components such as SCRs, diodes, and rectifiers, where standard fuses may not clear fast enough to prevent device damage during a fault event.

Key Features

• Voltage & Amperage Rating: Rated 500V and 25A, this fuse is sized for demanding semiconductor and power conversion circuit protection applications where accurate current sensing is critical.
• High Interrupt Rating: A 100 kAIC interrupt rating gives this fuse the capacity to safely clear high fault currents without compromising the protected circuit.
• High-Speed, Fast-Acting Design: As part of the Eaton Bussmann FWA series of high-speed fuses, this device is engineered to respond quickly to overcurrent conditions, helping protect semiconductor devices such as SCRs, diodes, and rectifiers from damaging short-duration current spikes that standard fuses may not clear in time.
• Non-Indicating Construction: This fuse uses a non-indicating body design, a standard configuration for many semiconductor fuse applications where visual blown-fuse indication is not required.
• Ferrule End x Ferrule End Termination: The dual ferrule end termination style is designed for compatibility with standard semiconductor fuse clips, blocks, and holders used in industrial power equipment.
• Eaton Bussmann Series Engineering: Manufactured under the Eaton Bussmann series product line, this fuse reflects Bussmann's long-standing reputation for dependable overcurrent protection components used across industrial and commercial power systems.
