Eaton FRN-R-2-8/10 Time-delay Fuse 2-8/10A 250V RK5

Product Description

The EATON FRN-R-2-8/10 is a dual-element, time-delay fuse rated at 2-8/10 amps and 250 volts, classified as Class RK5. It is designed to provide overcurrent protection in AC power distribution circuits while tolerating brief inrush currents from motors, transformers, and other inductive loads. The dual-element construction allows the fuse to carry harmless overloads momentarily without nuisance tripping, while still providing fast response to short-circuit faults. Licensed electricians and maintenance technicians install this fuse in panel boards, disconnect switches, and motor control equipment where selective coordination and reliable overload protection are required.

This fuse is suited for commercial and industrial electrical systems where motor branch circuits, feeder circuits, and power distribution equipment require dependable overcurrent protection. The Class RK5 rating places it in a category that provides enhanced short-circuit current interrupting performance compared to standard Class K fuses. Its compact form factor fits standard fuse holders and disconnect blocks designed for Class RK5 or Class K5 rejection-style fuses. This makes it a practical replacement for service and preventive maintenance work on existing equipment.

Key Features

• Dual-element, time-delay design tolerates motor inrush currents without nuisance opens
• 2-8/10 amp continuous current rating for precise circuit sizing
• 250 volt AC rating for standard single-phase and three-phase distribution circuits
• Class RK5 current-limiting construction provides high interrupting capacity
• Compatible with standard rejection-style fuse holders and disconnect switches

Compatibility

Designed as an OEM-style replacement for Class RK5 time-delay fuses used in residential, commercial, and industrial overcurrent protection applications.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit using proper LOTO procedures before removing or installing the fuse. Verify that the replacement fuse matches the ampere rating, voltage rating, and class of the original before installing. Never replace a fuse with one of a higher ampere rating than the circuit is protected for.
