The Fusetron FRN-R-4 Fuse is a time-delay, dual-element, Class RK5 fuse designed for use in residential and commercial applications. It is rated for up to 600 volts and is UL listed for motor circuit protection. The dual-element feature of this fuse provides additional protection to the circuit by allowing a slower response to over-current conditions. This helps protect against nuisance trips caused by temporary overloads. The FRN-R-4 fuse is available in three amperage ratings: 30A, 40A and 60A.
