FRN-R-90 - 90Amp Fuse

FRN-R-90 - 90Amp Fuse

When you need a 90-amp Class RK5 fuse and the equipment calls for FRN-R-90, getting the electrical ratings right matters. The Eaton Bussmann series FRN-R-90 is a dual-element fuse rated for 250 VAC and 125 VDC, with an interrupting rating of 200 kAIC at 250 VAC and 20 kAIC at 125 VDC. It has a 10-second response time at 500% of its rated current and uses a familiar blade-end-to-blade-end configuration. The fuse measures 5.88 inches long, 1 inch wide, and 1 inch high, so its specifications are easy to compare with those of the fuse being replaced or with the requirements of compatible equipment.

Material Compliance and Certifications

The FRN-R-90 is CE-marked in accordance with the manufacturer's specifications. Because fuse selection involves electrical safety, don't rely on amperage alone when identifying a replacement. Check the fuse class, AC or DC voltage, interrupting rating, connection type, and physical size against the requirements of the equipment being serviced.

Where It Works Best

The FRN-R-90 90A fuse is best suited to compatible electrical equipment and circuits that specifically require a Class RK5, dual-element fuse rated at 90 amps. Its 250 VAC and 125 VDC ratings allow it to serve compatible AC or DC applications, provided all of the equipment requirements fall within the fuse's published specifications.
