Cooper Bussmann FRS-R-60ID RK5 Time Delay Fuse 60A

Product Description

The COOPER BUSSMANN FRS-R-60ID is a cartridge-style, time delay fuse rated at 60 amps in the RK5 fuse class. It measures 5.5 inches in overall length and 1.06 inches in diameter, making it a standard-footprint replacement for fuse holder-mounted installations. This is a two-element, indicating fuse, meaning it provides a visual signal upon opening — a feature that speeds up fault diagnosis in the field. Rated for 20 kA interrupting capacity at DC 200 volts RMS, it delivers robust overcurrent protection in general-purpose electrical distribution applications. Electricians and maintenance technicians are the primary installers of this fuse type.

The FRS-R-60ID is suited for residential, commercial, and light industrial electrical systems where time delay protection is required to ride through normal inrush currents without nuisance opening. The RK5 class designation and cartridge body make it compatible with standard fuse holders and disconnect blocks designed for that class. Its indicating feature is particularly useful in panel or disconnect enclosures where quick visual fault identification reduces diagnostic time during service calls.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Always de-energize and lock out the circuit before removing or installing any fuse. Verify the fuse holder is rated for the RK5 class and the ampere rating of the replacement fuse before installation. Do not substitute a fuse of a higher ampere rating than the circuit is designed to carry.
