Eaton FRN-R-2/10 Time Delay Fuse 250V Class RK5

Product Description

The EATON FRN-R-2/10 is a time delay fuse rated at 250 volts and 0.2 amps, designed for Class RK5 fuse applications in electrical distribution and motor protection systems. This dual-element, time delay design allows the fuse to absorb temporary overloads and inrush currents without nuisance opening, while still providing fast response to sustained fault conditions. Licensed electricians and industrial maintenance technicians install this fuse in fusible disconnects, panelboards, and motor branch circuits where precise overcurrent protection is required.

This fuse is suited for commercial and industrial electrical systems that require Class RK5 rejection-style overcurrent protection. Typical applications include motor starter circuits, HVAC equipment branch circuits, and control panel power supplies where time delay characteristics help accommodate startup inrush without sacrificing short-circuit protection. Its compact size makes it a common selection for low-amperage branch circuit or control circuit protection tasks.

Key Features

• Time delay dual-element construction tolerates motor inrush and transformer magnetizing currents
• 250 volt AC rating suitable for standard single-phase and three-phase distribution circuits
• Class RK5 rejection feature prevents installation of lower-rated fuse classes in the same holder
• 0.2 amp (2/10 amp) rating provides precise protection for low-amperage control and instrumentation circuits
• Designed as a direct replacement for FRN-R series time delay fuses

Compatibility

Designed as an OEM-style replacement for Class RK5 time delay fuse applications in residential, commercial, and industrial electrical panels and fusible disconnects rated for 250 volts AC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for overcurrent protection devices. Always de-energize and lock out the circuit before removing or installing fuses. Verify that the fuse holder or fusible disconnect is rated for Class RK5 fuses and matches the voltage and amperage of this device. Do not substitute a fuse of a different class, voltage rating, or higher amperage in this application.
