FRS-R-100

600VAC maximum operating voltage capacity with a 100A continuous current rating and a dual-element, time-delay mechanism engineered for a massive 200,000A current-limiting interrupting threshold. | Heavy-Duty Class RK5 Dual-Element Time-Delay Current-Limiting Fusetron Fuse Unit Built with a Rejection-Style Knife-Blade Contact Assembly and a Flame-Retardant Fiberglass Tube Body. | Commercial building main electrical distribution panels, industrial manufacturing plant motor control centers, three-phase HVAC chiller power disconnect trunks, municipal water pump station safety switches. | FRS-R-100 | None | None | Bussmann FRS-R-100, Eaton FRS-R-100, Fusetron FRS-R-100 | Industrial Power Disconnect Overhaul: Pressed firmly into heavy-duty copper fuse clips inside a NEMA 3R enclosed safety switch housing using insulated high-voltage fuse pullers, then securely engaged into the line side of an industrial conveyor motor drive circuit to guarantee reliable short-circuit and thermal overload protection. | Bussmann / Eaton Fusetron RK5 Overcurrent Protection Systems: This premium current-limiting fuse was precision-engineered by Bussmann to provide up to 10 seconds of time-delay at 500% load, preventing nuisance fuse openings caused by high-inrush startup currents while providing tight backup thermal tracking inside commercial facility power frames, heavy-duty production plant platforms, and industrial branch-circuit distribution blocks.Manufacturer Exact Equals Matrix:Littelfuse: P/N FLSR100 (Class RK5 Dual-Element Time-Delay Fuse)Mersen / Ferraz Shawmut: P/N TRS100R (Tri-Onic Class RK5 Time-Delay Fuse)Edison Fuses: P/N ECSR100 (Class RK5 Dual-Element Time-Delay Fuse)Reliance Fuse: P/N FLSR100R (Class RK5 Current Limiting Fuse Array)Gould Shawmut: P/N TRS100R (Legacy Industrial Class RK5 Series Frame)CEFCO Fuses: P/N CRK100 (Dual-Element RK5 Time-Delay Series)Kirkwood Fuse: P/N KSRK100 (Class RK5 Industrial Safety Disconnect Element)Bussmann / Eaton: P/N FRS-R-100 (Original Reference Base Blueprint Part)
