Cooper Bussmann FRN-R-15 RK5 Time Delay Fuse 15A

Product Description

The COOPER BUSSMANN FRN-R-15 is a Class RK5 cartridge-style time delay fuse rated at 15 amps. It is designed for general-purpose overcurrent protection in branch circuits and equipment where motor loads, transformers, or other inductive loads require a fuse that tolerates brief startup surges without nuisance opening. The fuse measures 2 inches in overall length and 0.563 inches in diameter, with a dual-element internal construction. It carries CE, CSA, and UL listings and is installed by licensed electricians in fuse holders rated for RK5 Class fuses.

This fuse is suited for residential, commercial, and light industrial electrical systems where time delay protection is required on motor-branch or combination motor-controller circuits. The RK5 Class rating allows it to be used in applications calling for a current-limiting time delay fuse with high interrupting capacity. It mounts in a standard fuse holder and is sold individually, with a minimum order quantity of 10 units.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for fuse-based overcurrent protection. De-energize and lock out the circuit before removing or installing fuses. Verify the fuse holder is rated for Class RK5 fuses and matches the voltage and amperage of the replacement. Do not substitute a fuse of a different class or higher amperage rating than the circuit requires.
