Eaton BP/FRN-R-25 25A 250V Class R Time Delay Fuse 2-pack

Product Description

The EATON BP/FRN-R-25 is a dual-element, time-delay cartridge fuse rated at 25 amps and 250 volts, designed for motor branch-circuit protection in commercial and industrial electrical systems. Part of the Fusetron FRN-R series, it carries a UL-listed Class R rating with a 200,000 amp interrupting rating (AIR), making it suitable for circuits where high fault currents are a concern. The dual-element design allows normal motor inrush current at startup to pass without nuisance opening, while reliably interrupting sustained overloads and short-circuit faults before motor damage or burnout occurs. This pack includes two fuses. Installation is typically performed by licensed electricians working to NEC requirements.

This fuse is used in motor protection applications including HVAC equipment, pumps, compressors, and other single-phase or three-phase motor loads. It is well suited for motor disconnect switches, fusible safety switches, and motor control panels in residential, commercial, and light industrial settings. At the 25A rating, the fuse features ferrule-style ends, which are standard for FRN-R fuses rated from 1/10A through 60A. The time-delay characteristic helps prevent unnecessary trips caused by the high inrush currents typical of motor startup, while still providing protection against dangerous overload conditions.

Key Features

• Dual-element, time-delay design passes motor inrush current without nuisance tripping
• 25A rating with ferrule ends, consistent with FRN-R series fuses rated 1/10A to 60A
• 250V AC rating suitable for standard motor branch circuits
• UL-listed Class R with 200,000A interrupting rating (AIR)
• Protects motors from burnout caused by overloads and single-phasing conditions
• Sold as a 2-pack for convenient replacement stock

Compatibility

Designed as an OEM-style replacement Class R ferrule-end time-delay fuse for use in fusible safety switches, motor disconnects, and motor control panels rated for FRN-R series cartridge fuses at 25A and 250V.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing fuses. Verify that the fuse holder or disconnect is rated for Class R cartridge fuses at the appropriate voltage and amperage before installation. Do not substitute a higher-amperage fuse to address nuisance tripping without first diagnosing the underlying circuit or motor condition.
