FLSR030-ID - 30Amp Fuse

FLSR030-ID - 30Amp Fuse

Safeguard your industrial and commercial electrical systems with the Littelfuse  FLSR030ID 30 A, 600 V Time‑Delay Class RK5 Indicating Fuse. Designed for demanding applications, this cartridge‑style fuse features a dual‑element, time‑delay design that not only manages short circuits but sustains overloads, giving you dependable protection and increased uptime. The built‑in visual indicator makes it easy to see at a glance whether the fuse has tripped—no disassembly required—saving you valuable diagnosis time. With high interrupting ratings of up to 200 kA at 600 V AC and 20 kA at 300 V DC, this fuse thrives under heavy electrical stress and delivers long‑term durability even in harsh environments. Whether you’re outfitting motor control centers, HVAC systems, electrical distribution panels, pumps, or conveyors, the FLSR030ID provides the reliable circuit protection and quick maintenance feedback your operations demand.

Key Features and Benefits

• Dual‑Element / Time Delay Design: Provides effective protection against both short‑circuit events and sustained overload conditions, enhancing equipment longevity.
• Integrated Visual Indicator: Enables rapid blown‑fuse identification without removing equipment covers, reducing downtime and labor cost.
• High Interrupting Capacity: Rated at 200,000 A at 600 V AC and 20,000 A at 300 V DC, the fuse limits fault current and improves overall system safety.
• Cartridge Style Construction: Easy to mount and service in standard industrial fuse holders—minimal fuss, maximum reliability.
