FRS-R-25 - 25Amp Fuse

FRS-R-25 - 25Amp Fuse

Engineered for reliable circuit protection in industrial and commercial settings,  the FRS‑R‑25 from Eaton Bussmann delivers dependable performance when your systems can’t afford downtime. With a 25 A rating and compatibility across 600 V AC or 300 V DC circuits, this Class RK5 fuse is designed to guard motors, transformers, panelboards, and lighting systems from overloads and short circuits. Its dual‑element, time‑delay architecture provides flexibility for harmless surges, while its current‑limiting feature minimizes fault energy that could damage equipment. Designed with a 200 kA interrupt rating at 600 V AC and 20 kA at 300 V DC, this fuse stands ready to handle major fault events safely. Whether you’re protecting HVAC systems, industrial machinery, or general branch circuitry, the FRS‑R‑25 gives you the performance and simplicity you need, backed by Eaton’s reputation for quality.

Key Features and Benefits

• Dual‑Element Time‑Delay Design: Allows short, harmless surges (up to 500% of rated current for approx. 10 seconds) before opening, helping prevent unnecessary shutdowns.
• Current‑Limiting Capability: Reduces let‑through energy during short‑circuit events, protecting downstream components and reducing stress on panels and buswork.
• High Interrupt Rating: Rated at 200 kA at 600 V AC and 20 kA at 300 V DC — built to handle serious fault conditions confidently.
• Standard Ferrule Ends & Compact Size: Fits into existing fuse holders easily (approx. 5″L × 0.81″W × 0.81″H) for quick replacement and minimal downtime.
• CE Marked, UL/CSA Certified: Meets rigorous safety and performance standards so you can specify with confidence.

Where It Works Best

• The FRS‑R‑25 is an excellent choice for protecting motors, industrial machinery, HVAC units, panelboards, lighting systems, and transformer circuits—especially in applications where occasional surges are a normal part of operation and uninterrupted performance matters. Because of its time delay and dual‑element design, it’s ideal where start‑up currents or inrush loads may occur, and you want to avoid nuisance fuse openings.
