FRS-R-5 - 5Amp Fuse

FRS-R-5 - 5Amp Fuse

Designed for demanding industrial and commercial installations, the FRS‑R‑5 offers high‑fault‑current protection and inrush‑tolerant performance in a compact size. With a 5 A rating and dual‑element, time‑delay construction, it manages motor‑ and transformer‑type surge currents without nuisance interruptions—yet responds quickly to sustained overloads or short‑circuits. Rated at 600 V AC (300 V DC) and boasting an interrupting capacity of up to 200,000 A at 600 V AC and 20,000 A at 300 V DC, this Class RK5 fuse gives you peace of mind in critical circuits. Its non‑indicating design, ferrule‑end × ferrule‑end termination, and standard 5-inch body length mean excellent compatibility with most existing panels, motor starters, and control systems.

Key Features and Benefits

• Dual‑Element Time‑Delay Design: Lets harmless inrush currents (for example, from motors or large transformers) pass without tripping, while instantly protecting on sustained fault conditions.
• High Interrupting Capacity: 200 kA at 600 V AC, 20 kA at 300 V DC—ensuring safe operation in high‑fault‑current circuits.
• Compact, Install‑Ready Form Factor: A 5‑inch (L) × 0.81‑inch (W) × 0.81‑inch (H) cartridge with ferrule‑end terminations provides easy drop‑in replacement with minimal fuss.
• Reduced Service & Maintenance Needs: Because it handles surge currents gracefully and maintains cooler operation, you’ll see fewer trips and less downtime.
• Universal Compatibility: Fits standard Class RK5 fuse holders, control panels, motor circuits, HVAC systems and more without special adapters.

Where It Works Best

• The FRS‑R‑5 is ideal in applications where equipment uptime, reliable circuit protection, and tolerance of high inrush currents are essential—think motor control centers, conveyor systems, HVAC starter panels, automation machinery, and industrial power panels. If you’re managing motor loads, transformer loads or systems that face frequent startup surges, this fuse gives you effective protection without unnecessary trips or oversizing.
