The Bussmann BP/FNM-10 is a Type FNM 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 dangerous electrical overloads.
Time-delay fuses are engineered to tolerate brief inrush currents—such as those that occur when motors start up—without nuisance tripping, while still reliably interrupting sustained overloads that could cause overheating and fire hazards. The 10-amp, 250-volt rating makes these fuses suitable for both low-voltage and medium-voltage environments. Because they fit standard FNM midget fuse holders, they simplify retrofits and new installations without requiring special adapters.
Features and Benefits
- Time-Delay Technology: Handles temporary surge currents common in motor-driven applications while still interrupting sustained overloads to protect sensitive equipment.
- 10A/250V Rating: Delivers precise protection for circuits up to 250 volts in a ten-amp configuration.
- Compact Cartridge Design: Measures 13/32 x 1-1/2 inches and fits standard FNM midget fuse holders, minimizing downtime during maintenance and retrofits.
- High Interrupt Rating: 10 kA at 125 VAC and 200 A at 250 VAC interrupt capability ensures reliable performance under fault conditions.
- Melamine Body: Durable construction built for consistent performance in industrial panels, HVAC systems, and motor control centers.
- Two-Pack Convenience: Comes with two fuses securely packaged for organized storage and immediate installation.
