It features a dual-element construction that tolerates harmless inrush currents while responding quickly to sustained overloads and short circuits. The fuse body measures 5 inches in overall length and 20.6 mm in diameter, fitting standard RK1 fuse holders. With an interrupting capacity of 100 kA at DC and 300 kA at AC (RMS), this fuse is suited for circuits where high available fault current is a concern. Licensed electricians and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fuse is intended for use in industrial control panels, motor branch circuits, and power distribution equipment where RK1 class protection is specified. The time delay characteristic makes it well suited for motor starter circuits, transformer primaries, and other loads that draw elevated inrush current on startup without indicating a fault condition. It mounts in a standard RK1 fuse holder and is sold individually, with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8 amp rating with time delay characteristic for inrush-tolerant circuit protection\u003c\/li\u003e\n  \u003cli\u003eRK1 fuse class with dual-element construction\u003c\/li\u003e\n  \u003cli\u003e100 kA interrupting rating at DC, 300 kA at AC (RMS)\u003c\/li\u003e\n  \u003cli\u003eOverall length of 5 inches (127 mm), diameter of 20.6 mm\u003c\/li\u003e\n  \u003cli\u003eNon-indicating fuse body in standard cartridge form factor\u003c\/li\u003e\n  \u003cli\u003eCE Certified, CSA Certified (C22.2 No. 248.12), and UL Listed (Guide JDDZ File E4273)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for RK1 class cartridge fuse applications requiring a 5-inch, 8 amp time delay fuse in a standard fuse holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing a fuse. Verify that the replacement fuse matches the amperage, voltage, and class marked on the original equipment nameplate.
