FRS-R-12 - 12Amp Fuse Description
FRS-R-12 - 12Amp Fuse
The Eaton Bussmann FRS-R-12 is a 12-amp12-amp Class RK5 fuse designed for electrical equipment that requires a dual-element fuse with ferrule-style connections. Rated for 600 VAC and 300 VDC, it has an interrupting rating of 200 kAIC at 600 VAC and 20 kAIC at 300 VDC. Its published response time is 10 seconds at 500% of rated current. Those details matter when you're replacing a fuse: matching the 12A rating is only part of the job. Checking the fuse class, voltage, interrupting rating, connection style, and dimensions helps confirm that the FRS-R-12 fuse is the right fit for the equipment you're servicing.
