The Bussmann BP/FRN-R-30ID Fusetron cartridge fuse is a dual-element, time-delay fuse designed to protect motors, transformers, and electrical distribution circuits from overcurrent and short-circuit damage. This 30-amp, 250-volt fuse combines superior protection with reliable performance across a wide range of applications, from industrial motor circuits to household lighting and heating systems.
Time-delay technology allows brief startup current surges typical of motor inrush to pass through safely, while blocking dangerous sustained overloads before equipment burnout occurs. The Class RK5 current-limiting design limits fault currents, protecting both wiring and connected equipment. An indicating label darkens visually when the fuse has opened, making it easy to identify blown fuses at a glance. This two-pack provides convenient replacement fuses for immediate availability.
Features and Benefits
- Dual-Element Design: Allows closer sizing to the actual load, providing superior protection for motors and transformers while minimizing nuisance trips.
- Time-Delay Technology: Safely tolerates brief inrush currents during motor startup while responding quickly to sustained dangerous overloads.
- Class RK5 Current Limiting: Limits fault currents to protect equipment and wiring from damage during short circuits.
- Visual Indicating Label: Darkens when the fuse opens, making it simple to identify blown fuses without testing.
- Broad Application Range: Suitable for AC power distribution mains, feeders, branch circuits, motors, transformers, lighting, heating, and other loads.
- Two-Pack Convenience: Includes two 30-amp fuses for ready replacement and backup protection.
