FRS-R-2 - 2Amp Fuse

FRS-R-2 - 2Amp Fuse

When your application demands dependable circuit protection in industrial or commercial settings, the Eaton Bussmann FRS‑R‑2 delivers. This premium Class RK5, dual‑element, time‑delay fuse is rated at 2 amps and designed to handle surge currents (such as motor startups or transformer inrush) without nuisance tripping. With a voltage rating of 600 V AC / 300 V DC and an interrupting capacity of up to 200 kA at 600 V AC and 20 kA at 300 V DC, the FRS‑R‑2 helps safeguard branch circuits, control panels, motors, and transformers from both overloads and short‑circuits. The ferrule‑end design allows for straightforward installation into standard holders, making it a sound choice when you need performance, reliability and ease of maintenance.

Key Features and Benefits

• Time‑Delay Dual‑Element Design: Allows temporary overloads (like motor or transformer inrush) without immediately blowing the fuse, reducing costly downtime due to nuisance trips.
• High Interrupting Capacity: Rated up to 200 kA at 600 V AC and 20 kA at 300 V DC—ideal for protecting downstream equipment under severe fault conditions.
• 600 V AC / 300 V DC Capability: Supports both AC and DC systems in one versatile solution.
• Compact Cartridge Form‑Factor: At approximately 5 in long × 0.81 in wide and weighing just ~0.15 lb, it’s easy to handle and install even in tight panel spaces.
• Efficient Operation: Designed to operate cooler and more effectively than standard fuses thanks to its current‑limiting, dual‑element construction—supporting longer equipment life and lower overall maintenance.
