The Bussmann BP/FRN-R-30 is a time-delay cartridge fuse designed to provide motor overload, ground fault, and short-circuit protection in industrial panels, motor starters, and HVAC equipment. This 30-amp, 250-volt fuse is engineered to handle the inrush currents that occur during motor startup and transformer energization, preventing nuisance trips while protecting sensitive loads from damage.
Time-delay fuses are essential for circuits that experience temporary current surges. This fuse will hold an overload five times greater than its 30-amp rating for a minimum of ten seconds, allowing motors and transformers to start without interruption while still protecting equipment against sustained overloads and single-phase conditions on three-phase systems. The fiberglass cartridge body is compact and fits easily into tight panel spaces, and the two-pack ensures you have a spare for critical applications.
Features and Benefits
- Time-delay protection: Tolerates temporary inrush currents without nuisance trips, ideal for motor start-up and transformer inrush events.
- Motor and equipment protection: Provides overload, ground fault, and short-circuit protection while helping prevent motor burnout from overloads and single phasing on three-phase systems.
- 250 VAC / 125 VDC rated: Certified for standard low-voltage applications with a 200 kA interrupt rating for reliable performance.
- Compact cartridge design: Measures 2.375 inches long by 1.375 inches wide by 0.25 inches high, fitting easily into industrial panel spaces.
- Two-pack value: Includes two fuses, offering redundancy for critical systems and ensuring a spare is available.
- UL listed and CSA certified: Meets stringent safety standards for electrical protection and reliability.
