Bussmann FNQ-1/10 500V Midget Time-Delay Fuse

Bussmann FNQ-1/10 500V Midget Time-Delay Fuse

The Bussmann FNQ-1/10 is a 500V Midget-style time-delay (TD) fuse designed to provide dependable, code-compliant overcurrent protection in a compact footprint. Rated at 1/10A, this fuse is purpose-built for circuits that call for precise, low-current protection, while its time-delay characteristic allows it to ride through momentary current surges, inrush events, and temporary overload conditions without opening unnecessarily. As part of the Bussmann FNQ series of Midget fuses, the FNQ-1/10 is a proven choice for electricians, panel builders, OEMs, and maintenance professionals who need a compact, reliable fuse for control circuits, instrumentation, and other low-amperage applications. Bussmann Midget fuses are widely selected for their small size relative to standard fuse classes, making them ideal where panel space is at a premium. Its Midget form factor allows it to fit standard Midget-style fuse holders and fuse blocks commonly used in industrial and commercial control panels, saving valuable panel space compared to larger fuse classes.

Key Features

• Amperage Rating: 1/10A rating delivers precise overcurrent protection tailored to low-current control and instrumentation circuits, helping prevent damage from sustained overcurrent conditions.
• Voltage Rating: Rated 500V, giving this fuse the voltage headroom needed for a wide range of circuit voltage applications found in commercial and industrial electrical systems.
• Midget Fuse Design: Compact Midget-style fuse body is sized to fit standard Midget fuse holders, fuse blocks, and disconnect switches, making it easy to specify as a drop-in replacement in existing installations.
• Time-Delay (TD) Construction: Time-delay fuse element is engineered to ride through temporary current surges and inrush conditions, such as motor starting current, without opening, reducing nuisance fuse replacement.
• FNQ Series: Part of the established Bussmann FNQ family of Midget time-delay fuses, built for consistent, repeatable performance across production lots.
• Space-Saving Format: The Midget fuse class occupies less physical space than larger fuse types, supporting higher packing density in fuse panels and disconnect blocks.
• Compact Footprint: The Midget fuse form factor saves panel and enclosure space compared to larger fuse classes, supporting compact panel design.
