It is designed for general-purpose overcurrent protection in control circuits, motor branch circuits, and equipment panels where a time delay characteristic is required to ride through inrush currents without nuisance tripping. The fuse body measures 2 inches in overall length and 0.563 inches in diameter. It is a dual-element, non-indicating fuse that mounts in a standard fuse holder. Licensed electricians and industrial maintenance technicians install this fuse as part of panel and equipment servicing work.\u003c\/p\u003e\u003cp\u003eThis fuse is suited for residential, commercial, and light industrial electrical systems where Class RK5 time delay protection is specified. It is commonly installed in disconnect switches, fuse blocks, and equipment control panels that call for a 2.25-amp time delay fuse. The two-element design allows the fuse to carry normal motor starting currents while still opening reliably on sustained overloads or short-circuit faults. It is a single unit per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass RK5 time delay cartridge fuse rated at 2.25 amps\u003c\/li\u003e\n\u003cli\u003eDual-element design handles motor inrush without nuisance tripping\u003c\/li\u003e\n\u003cli\u003eNon-indicating fuse body in standard cartridge form factor\u003c\/li\u003e\n\u003cli\u003eMounts in standard fuse holders for easy replacement\u003c\/li\u003e\n\u003cli\u003eCE Certified, CSA Certified, and UL Listed to published standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for Class RK5 time delay cartridge fuses in standard fuse holders requiring a 2.25-amp, 2-inch cartridge fuse.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes.
