It is designed for general-purpose overcurrent protection in branch circuits and equipment where motor loads and inrush currents demand a time-delay response. The fuse features a dual-element construction that tolerates temporary overloads without nuisance opening, while still clearing sustained overcurrents and short circuits quickly. The indicating function signals a blown fuse state, speeding up troubleshooting. Licensed electricians and maintenance technicians install this fuse in industrial panels, motor control centers, and commercial electrical distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis fuse fits standard Class RK1 fuse holders and is suited for branch-circuit protection of motors, transformers, and similar inductive loads in residential, commercial, and light industrial applications. Its 35 A rating covers a wide range of single-phase and three-phase motor branch circuits where a time-delay fuse is specified by the equipment manufacturer or the NEC. The cartridge body measures 3 inches in overall length and fits holders designed for Class RK1 fuses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClass RK1 time-delay dual-element design tolerates motor inrush without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003e35 A continuous rating for branch-circuit and equipment protection\u003c\/li\u003e\n  \u003cli\u003e100 kA interrupting rating at DC and 300 kA at AC (RMS) for high fault-current environments\u003c\/li\u003e\n  \u003cli\u003eIndicating feature provides visible blown-fuse signal to reduce diagnostic time\u003c\/li\u003e\n  \u003cli\u003eCartridge body mounts in standard RK1 fuse holders\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 Class RK1 cartridge fuse applications.
