FRS-R-30 - 30Amp Fuse

FRS-R-30 - 30Amp Fuse

The 30 Amp Class RK5 dual‑element time‑delay fuse from the Bussmann / Eaton FRS‑R series is built for installations where safety, uptime, and smooth operation are non‑negotiable. With ratings of 600 Vac and 300 Vdc, and an interrupting capacity of up to 200 kA at 600 Vac (20 kA at 300 Vdc), it gives you the confidence that your circuits are protected when faults or overloads occur. This fuse is purpose‑designed for environments with inductive loads or motor startups — its 10‑second delay at 500% of rated current ensures that temporary surges don’t nuisance‑trip the circuit while still shutting things down when a true fault hits. It’s a smart choice when you want reliable protection without compromising performance.

Key Features and Benefits

• Current-limiting capability: Helps reduce let‑through energy and protects downstream electronics and wiring during fault events.
• Time‑delay (10 seconds at 500% rated current): Allows circuits to ride through temporary overloads (such as motor inrush) without blipping offline, yet still respond promptly to serious problems.
• Dual‑element design: Optimized for both overload and short‑circuit protection, enabling tighter fuse sizing and cost savings on supporting equipment.
• Ferrule‑end terminals: Ensure quick installation into standard Class R holders, keeping your maintenance or replacement time down.
• High interrupt rating: 200 kA at 600 Vac and 20 kA at 300 Vdc mean this fuse will handle severe fault conditions in demanding industrial settings.
• Non‑indicating model: Suited for controlled environments or applications where a fuse‑open indicator isn’t required.

Where It Works Best

• This fuse is ideal for industrial control panels, HVAC motor starters, motor control centres, machinery disconnect units or power distribution gear. Its ability to handle inrush currents without nuisance tripping makes it perfect for motors, transformers, or other inductive loads. If you’re looking for reliable protection in a demanding environment — and you want to avoid repeated false trips while still maintaining safety under real fault conditions — this model is a solid choice.
