Bussmann FNA-1-6/10 Midget Time-Delay Fuse

Bussmann FNA-1-6/10 Midget Time-Delay Fuse, 125V

The Bussmann FNA-1-6/10 Midget Time-Delay Fuse is a compact 125V overcurrent protection device engineered for control circuits, control transformers, and equipment that requires dependable time-delay fuse protection. Carrying the FNA-1 series designation, this midget-style TD (time-delay) fuse is built to withstand momentary inrush current and brief overload conditions without nuisance opening, while still interrupting the circuit reliably under sustained fault or overcurrent conditions. Sized to fit standard midget fuse holders and fuse blocks, it offers a space-saving overcurrent protection solution for panels and equipment with limited mounting space. It is manufactured by Bussmann, a recognized supplier of fuses and circuit protection products for commercial, industrial, and OEM electrical systems.

Key Features

• Voltage Rating: 125V rating suited for control circuits, control transformers, and other low-voltage equipment protection applications where a 125V-rated fuse is required.
• Midget Fuse Form Factor: Compact midget-style body sized to fit standard midget fuse holders, fuse blocks, and disconnect switches, making it ideal for space-constrained panels and equipment.
• Time-Delay (TD) Operation: Time-delay design allows the fuse to ride through brief inrush current and temporary overload conditions without nuisance opening, while still opening reliably to protect the circuit under sustained overcurrent conditions.
