FRS-R-15 - 15Amp Fuse

FRS-R-15 - 15Amp Fuse

The FRS‑R‑15 from Eaton (Bussmann division) is engineered for demanding industrial and commercial electrical systems where motor starts, transformer inrush, and other surge conditions must be handled—yet sustained overloads and short circuits need to be cut off quickly. Thanks to its dual‑element, time‑delay design, it tolerates momentary startup currents while providing dependable protection under fault conditions. With a 600 Vac / 300 Vdc rating, an interrupting capacity up to 200 kA at 600 Vac and 20 kA at 300 Vdc, and a compact 5‑inch form factor that fits standard RK5 fuse holders, this fuse is built to deliver lasting performance and peace of mind when continuity, safety, and compliance matter most.

Key Features and Benefits

• Time‑Delay Dual‑Element Design: Provides a brief hold‑off for equipment startup surges and a firm trip on actual overloads—helping avoid nuisance interruptions.
• High Current‑Limiting Capability: Cuts fault energy and limits damage to downstream equipment during short‑circuit events by rapidly interrupting high‐fault currents.
• Standard‑Size Cartridge: The 5 in × 0.81 in form makes it simple to drop into existing Class RK5 fuse holders with ferrule‑end terminations—no custom adaptations required.
• Reliable Performance for Critical Systems: Designed for minimal interruption and maximum uptime in motor control centers, lighting panels, HVAC systems, and industrial automation environments.
