Bussmann FRN-R-60 Fusetron 60A Dual-Element Time-Delay Cartridge Fuse 250V

The Bussmann FRN-R-60 is a 60-Amp Fusetron dual-element, time-delay cartridge fuse rated for 250V AC circuits. Manufactured by Bussmann (a Cooper Industries brand), this Class RK5 fuse is designed to provide reliable overcurrent protection in demanding industrial, commercial, and residential electrical applications.

The dual-element design provides two distinct levels of protection: it tolerates temporary motor starting surges and harmless inrush currents without nuisance tripping, while still delivering fast, precise response to damaging short-circuit conditions. This makes the FRN-R series a go-to choice for motor branch circuit and feeder protection.

Key Features:

• Amperage: 60 Amps
• Voltage Rating: 250V AC
• Fuse Class: RK5
• Type: Dual-element, time-delay
• Form Factor: Cartridge (rejection-type ferrule)
• Interrupting Rating: 200,000 Amps RMS Symmetrical
• Standards: UL Listed, CSA Certified
• Rejection-type ferrule body helps prevent accidental installation of non-time-delay fuses in Class RK5 holders
• Suitable for motor circuits, transformers, solenoids, and other inductive loads

The FRN-R-60 installs in standard Class R or Class H fuse holders and disconnect switches accepting 60A cartridge fuses. Its time-delay characteristic allows motors up to 60A FLA to start without blowing the fuse, while still protecting wiring and equipment from sustained overloads and fault currents.
