Cooper Bussmann 20-amp 125v Type Fnm Time Delay Cartridge Midget Fuse, 2-pk.
Videos
The Bussmann BP/FNM-20 is a time-delay cartridge fuse designed to provide supplemental protection for industrial, commercial, agricultural, heating, ventilating, and air conditioning equipment. This compact midget fuse protects internal components such as control circuit wiring, motor control transformers, and small motors from overload damage while accommodating temporary inrush currents that would otherwise cause nuisance interruptions.
Time-delay fuses are essential safety components that distinguish between brief power surges and sustained overloads. Unlike standard fuses, the FNM design allows momentary surge currents to pass through without tripping, yet reliably interrupts dangerous sustained overloads. This dual capability helps extend the service life of sensitive equipment and reduces costly downtime in critical applications.
Features and Benefits
- Time-Delay Technology: Permits short-term inrush currents while guaranteeing interruption of sustained overloads, protecting motors and transformers from nuisance trips.
- 20-Amp Rating: Precisely calibrated 20-ampere protection suitable for control circuits, motor loads, and low-voltage applications.
- 250V Maximum Rating: Rated for 250-volt systems with a 10 kA interrupt rating.
- Compact Cartridge Form: Midget size design fits securely in standard fuse holders, saving valuable panel space in tight installations.
- Melamine Body: Durable cartridge construction for reliable performance.
- Two-Pack Supply: Includes a spare fuse for immediate replacement, minimizing service interruptions and downtime.
