FLSR200-ID - 200Amp Fuse

FLSR200-ID - 200Amp Fuse

Protect your high‑demand electrical systems with the Littelfuse FLSR200ID — a premium 200‑amp, 600-volt AC (and 300-volt DC) Class RK5 indicating fuse crafted for industrial and commercial use. This dual‑element, time‑delay (Slo‑Blo) fuse is designed to manage motor startups, transformer energization, and high inrush current events without nuisance trips, while the built‑in visual indicator instantly shows when the fuse has blown — speeding up maintenance and helping keep downtime to a minimum. With knife‑blade terminals for low‑resistance connections and a current‑limiting design that reduces stress on downstream components during faults, the FLSR200ID is ideal when reliability and uptime are critical.

Key Features and Benefits

• Built‑In Fuse Status Indicator: A visual “window” instantly signals a blown fuse, so maintenance staff don’t have to guess or test manually.
• Dual‑Element Time‑Delay Design: Handles temporary inrush currents without opening, while still responding rapidly to sustained overloads.
• Knife‑Blade Terminals: Provide secure, low‑resistance connections for dependable installation in demanding environments.
• Current‑Limiting Capability: Helps restrict fault currents, reducing damage to wiring and downstream equipment.
• High Interrupting Ratings: Prepares your system for worst‑case fault conditions, ensuring safety and system protection.
