Description
The Bussmann FNQ-R-3/4 is a 600V, 3/4 amp time delay midget fuse engineered for dependable overcurrent and short-circuit protection in HVAC control circuits, motor branch circuits, and industrial applications. Its time delay characteristic allows the fuse to withstand harmless temporary inrush currents — such as motor starting surges — without nuisance tripping, while still responding quickly to sustained overloads and fault conditions.
Key Features
- Voltage rating: 600V AC
- Amperage rating: 3/4 A (0.75A)
- Time delay action for tolerance of motor inrush and startup surges
- Class CC midget fuse form factor for compact control panel installations
- Suitable for use in HVAC control circuits, transformers, and small motor applications
- Manufactured by Bussmann, a trusted leader in circuit protection
Application
The FNQ-R-3/4 is ideal for protecting low-amperage control circuits in commercial and residential HVAC systems, including transformer secondary circuits, fan coil units, and other sensitive control wiring where precise overcurrent protection is required. The time delay feature makes it especially well-suited for motor loads where momentary inrush current would otherwise cause nuisance fuse failures.
