Cooper Bussmann BP/FRS-R-30 Cartridge Fuse 30A 600V

Product Description

The COOPER BUSSMANN BP/FRS-R-30 is a Type FRS-R time-delay cartridge fuse rated at 30 amps and 600 volts. Sold in a carded 5-pack, this Fusetron-series fuse is built for circuits that carry motors, transformers, and other inductive loads where harmless inrush current would trip a fast-acting fuse unnecessarily. The time-delay characteristic lets the fuse ride through short-duration overloads while still clearing hard faults quickly. At 5 inches in length and 0.81 inches in diameter, it fits standard Class RK5 fuse holders and disconnect blocks common in HVAC, refrigeration, and industrial control panels.

This fuse is suited for residential and light commercial HVAC equipment, motor control centers, pump panels, and refrigeration systems where a dual-element, time-delay fuse is specified. Electrical contractors, HVAC technicians, and industrial maintenance trades use the FRS-R series as a standard replacement in fusible disconnects and load centers. The carded retail packaging makes it practical for field service inventory as well as shop stock.

Key Features

• 30-amp rating with 600-volt AC maximum voltage for broad panel compatibility
• Dual-element time-delay design handles motor inrush without nuisance blowing
• Type FRS-R Class RK5 form factor fits standard rejection-style fuse holders
• 5-inch length and 0.81-inch diameter match common cartridge fuse block dimensions
• Carded 5-pack format for easy field restocking and job-site use

Compatibility

Designed as a direct replacement for Type FRS-R Class RK5 cartridge fuse positions in fusible disconnects, load centers, and motor-circuit fuse holders rated for 600 volts AC.

Installation Notes

Fuse replacement must be performed by a qualified electrician in accordance with NFPA 70 (NEC) requirements. Always open, lock out, and tag out the disconnect before removing or installing fuses. Verify the replacement fuse amperage and voltage rating match the circuit overcurrent protection requirements before energizing. Never substitute a higher-amperage fuse to resolve nuisance blowing without first identifying the underlying cause.
