FRS-R-200 - 200Amp Fuse

FRS-R-200 - 200Amp Fuse

Engineered for high‑demand industrial and commercial power systems, the FRS‑R‑200 from the Eaton Bussmann line delivers dependable over‑current protection where it counts. Rated at 200 amps, 600 V AC and 300 V DC, this Class RK5, time‑delay fuse is built with a dual‑element, current‑limiting design that tolerates short motor inrushes without nuisance trips—while still responding swiftly to genuine fault conditions (it activates in roughly 10 seconds at 500% of rated current). It boasts a high interrupting capacity—200 kA at 600 V AC and 20 kA at 300 V DC—so it’s well‑suited for circuit protection zones with heavy fault potential. At just about 5 inches long and under 1 lb in weight, installation into standard RK5 fuse holders is straightforward. Whether protecting motor control centers, distribution panels, transformers, or HVAC systems, this fuse gives you a smart combination of protection, performance, and space efficiency.

Key Features and Benefits

• Efficient current‑limiting action: Restricts let‑through energy during short circuits, helping safeguard downstream equipment and reducing arc‑flash risk.
• Time‑delay, dual‑element construction: Handles temporary surge currents (such as motor starts) without unnecessary trips, yet still protects against genuine overloads and faults.
• Compact and lightweight: At approximately 5″ in length and under 1 lb, it fits standard blade‑end fuse blocks with ease.
• Blade‑end terminals: Provides secure, stable connection in compatible fuse holders and simplifies installation or replacement.
• High interrupting capacity: Rated at 200 kA interrupting at 600 V AC (and 20 kA at 300 V DC), so it is capable of handling severe fault conditions with confidence.
• Class RK5 rating: Meets proven industry standard for branch‑circuit protection in demanding commercial/industrial settings.

Where It Works Best

• This FRS‑R‑200 Fuse performs exceptionally in demanding applications such as heavy‑duty motor control centers, large HVAC systems, commercial distribution panels, factory power systems, and energy distribution networks. Use it in circuits that handle large surge currents—transformers, motors starting up, or heavy machinery—and where you need reliable short‑circuit and overload protection without the nuisance trips that can stall operations. By deploying this fuse in the right place you’ll ensure continuous operation, fewer downtime surprises, and long‑term protection for your critical assets.
