Cooper Bussmann BP/FRN-R-30 Cartridge Fuse 30A 250V

Product Description

The COOPER BUSSMANN BP/FRN-R-30 is a Type FRN-R time-delay cartridge fuse rated at 30 amps and 250 volts. It uses a Fusetron time-delay design that tolerates brief inrush currents without nuisance tripping, while still providing reliable overcurrent protection during sustained fault conditions. This package contains two fuses and arrives carded for easy retail or shop storage. Electricians, HVAC technicians, and industrial maintenance professionals install this fuse type in motor circuits, HVAC equipment, and other loads that draw high startup current before settling to normal operating amperage.

Type FRN-R fuses are a dual-element, time-delay class RK5 fuse commonly specified for motor branch-circuit protection in residential and light commercial applications. They are well suited for air conditioning condensing units, compressors, fans, and similar motor loads where startup inrush must be tolerated without compromising short-circuit protection. The carded two-pack format makes this a practical choice for service vans and shop stock where replacements are needed on the job.

Installation Notes

Cartridge fuse installation and replacement should be performed by a qualified electrician in accordance with NEC guidelines. Always de-energize and lock out the circuit before opening a fuse block or disconnect. Use an appropriately rated fuse puller tool to remove and install cartridge fuses safely. Verify the replacement fuse amperage, voltage, and type match the overcurrent device specification on the equipment nameplate before installing.
